Description

[0001] PREPARATION OF COMPOUND AND CRYSTALLINE FORMS THEREOF

[0002] FIELD OF THE INVENTION

[0003] The present invention belongs to the field of medicinal chemistry, and more specifically provides a preparation method of a therapeutic compound and its crystallized form.

[0004] BACKGROUND

[0005] TEA domain transcription factors (TEAD proteins) are effectors for oncogenic YAP / TAZ signaling in cancers with deregulated Hippo tumor suppressor pathway signaling. The interaction between Yesl Associated Transcriptional Regulator (YAP1, aka YAP), WW domain-containing Transcription Regulator 1 (WWTR1, aka TAZ), a transcriptional coactivator paralog to YAP, and TEAD proteins was demonstrated both in vitro and in vivo. In both cases, the interaction of the proteins leads to increased TEAD transcriptional activity and expression of genes involved in proliferation, survival, angiogenesis, and other hallmarks of cancer. In normal tissues, intact Hippo signaling via MST1 / 2 and LATS1 / 2 kinases results in phosphorylation of YAP / TAZ, sequestration in the cytoplasm and proteosomal degradation. Inactivation of Hippo signaling as a result of somatic mutations in NF2, MST or LATS stabilizes YAP / TAZ and leads to nuclear translocation, association with TEAD, and activation of TEAD target genes. Genomic amplification of YAP / TAZ, or gene fusions resulting in constitutively active YAP / TAZ, are alternative mechanisms of Hippo pathway deregulation. In addition, activation of YAP / TAZ signaling has been described as a mechanism of resistance to other targeted cancer therapies, such as inhibitors of EGFR and MEK.

[0006] Accordingly, inhibitors of TEAD 1, 2, 3 and / or 4, can have great potential in the application of cancer therapy, both as monotherapy in cancers with deregulated Hippo pathway signaling and as combination therapy with other targeted agents.

[0007] The compound (R, £)-l-(3-(4-(trifluoromethyl)styryl)pyrrolidin-l-yl)prop-2-en-l-one as a covalent inhibitor of YAP / TAZ-TEAD oncoproteins is described in patent application No. PCT / US23 / 23957. DETAILED DESCRIPTION

[0047] Definitions As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. Thus, for example, references to “the method” includes one or more methods, and / or steps of the type described herein which will become apparent to those persons skilled in the art upon reading this disclosure. The term “about” will be understood by persons of ordinary skill in the art. Whether the term “about” is used explicitly or not, every quantity given herein refers to the actual given value, and it is also meant to refer to the approximation to such given value that would be reasonably inferred based on the ordinary skill in the art. Reference to “about” a value or parameter herein includes (and describes) variations that are directed to that value or parameter per se. For example, description referring to “about X” includes description of “X” As used herein , and unless otherwise specified, the terms “about” and “approximately,” when used in connection with temperatures, doses, amounts, or weight percent of ingredients of a composition or a dosage form, mean a dose, amount, or weight percent that is recognized by those of ordinary skill in the art to provide a pharmacological effect equivalent to that obtained from the specified dose, amount, or weight percent. Specifically, the terms “about” and “approximately,” when used in this context, contemplate a dose, amount, or weight percent within 15%, within 10%, within 5%, within 4%, within 3%, within 2%, within 1%, or within 0.5% of the specified dose, amount, or weight percent.

[0048] As used herein, “crystalline” refers to a solid form of Compound I, wherein there exists long- range atomic order in the positions of the atoms. The crystalline nature of a solid can be confirmed, for example, by examination of the X-ray powder diffraction pattern. If the XRPD shows sharp intensity peaks in the XRPD then the compound is crystalline. A solid form of Compound I that is “crystalline” is a solid that is completely crystalline or partially crystalline, and encompasses solids that are at least 80% crystalline, 85% crystalline, 90% crystalline, 95% crystalline, and 99% crystalline, by weight. Crystalline solids are ordered arrangements of molecules that possess distinguishable crystal lattice or unit cell, and consequently have definable long range ordering. In some embodiments, substantially crystalline refers to a solid form of Compound I that is at least 80% crystalline. In other embodiments, substantially crystalline refers to a solid form that is at least 90% crystalline.

[0049] As used herein, chemical purity refers to extent to which the disclosed form is free from materials having different chemical structures. Chemical purity of the compound in the disclosed crystal forms means the weight of the compound divided by the sum of the weight of the compound plus materials / impurities having different chemical structures multiplied by 100%, i.e., percent by weight. In one embodiment, the compound in the disclosed crystalline forms has a chemical purity of at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or at least 99% by weight.

[0050] The term “hydrate” refers to a crystalline Compound I where a stoichiometric or non- stoichiometric amount of water is incorporated into the crystal structure. A hydrate is a solvate wherein the solvent incorporated into the crystal structure is water. The term “anhydrous” when used with respect to a compound means substantially no solvent incorporated into the crystal structure, e.g., less than 0.1% by weight as determined by Karl Fisher analysis. A compound that is anhydrous is referred to herein as an “anhydrate”.

[0051] The term “amorphous” means a solid that is present in a non-crystalline state or form. Amorphous solids are disordered arrangements of molecules and therefore possess no distinguishable crystal lattice or unit cell and consequently have no definable long range ordering. Solid state ordering of solids may be determined by standard techniques known in the art, e.g., by X-ray powder diffraction (XRPD) or differential scanning calorimetry (DSC). Amorphous solids can also be differentiated from crystalline solids e.g., by birefringence using polarized light microscopy.

[0052] A single crystalline form of Compound I means that (R, E)-l-(3-(4-

[0053] (trifluoromethyl)styryl)pyrrolidin-l-yl)prop-2-en-l-one is present as a single crystal or a plurality of crystals, in which each crystal has the same crystalline form (z.e., crystalline form I or II). When the crystal form is defined as a specified percentage of one particular single crystalline form of the compound, the remainder is made up of amorphous form and / or crystalline forms other than the one or more particular forms that are specified. In one embodiment, the crystalline form is at least 60% a single crystalline form, at least 70% a single crystalline form, at least 80% a single crystalline form, at least 90% a single crystalline form, at least 95% a single crystalline form, or at least 99% a single crystalline form by weight. Percent by weight of a particular crystal form is determined by the weight of the particular crystal form divided by the sum weight of the particular crystal, plus the weight of the other crystal forms present plus the weight of amorphous form present multiplied by 100%.

[0054] The 2-theta values of the X-ray powder diffraction patterns for the crystalline forms described herein may vary slightly from one instrument to another and also depending on variations in sample preparation and batch to batch variation. Therefore, unless otherwise defined, the XRPD patterns and / or the 2-theta peak values recited herein are not to be construed as absolute and can vary by ± 0.2 degrees. The 2-theta values provided herein were obtained using Cu, k- Alpha radiation.

[0055] Temperature values, e.g., for DSC peak temperatures and DSC onset temperatures herein may vary slightly from one instrument to another and also depending on variations in sample preparation, the rate of temperature increases over the course of the experiment, batch to batch variation of the material, and other environmental factors. Therefore, unless otherwise defined, temperature values recited herein are not to be construed as absolute and can vary by ± 5 degrees.

[0056] “Substantially the same XRPD pattern” or “an X- ray powder diffraction pattern substantially similar to” a defined figure means that for comparison purposes, at least 90% of the peaks shown are present. It is to be further understood that for comparison purposes some variability in 2-theta peak positions from those shown is allowed, such as ± 0.2 degrees. It should be understood that when the expression “characterized by X-ray powder diffraction peaks at 29 angles (± 0.2°)” followed by a list of 2-theta peak positions that the ± 0.2 degrees applies to each and every one of the peak positions listed.
