Embodiment 1

[0170] Embodiment 1: Preparation of crystal form CM-I

[0171] Weigh 500 mg of the compound of formula (I), dissolve it in 27 mL of ethanol at 50° C., and filter. The filtrate was added dropwise to 200mL water at 20°C, stirred for 2h, and filtered. The wet filter cake was vacuum-dried at 25°C for 24 hours, and the obtained solid was the crystal form CM-I of the compound of formula (I). Carry out XRPD test to the obtained solid, its X-ray powder diffraction data are as shown in table 1, and its XRPD pattern is as follows figure 1 Shown; Carry out TGA test to gained solid, its spectrogram is as figure 2 As shown, the weight loss is about 10.5% at 25-100°C; DSC test is performed on the obtained solid, and there are two endothermic peaks at 60°C-92°C, and one exothermic peak at 170°C-185°C. image 3 Shown; Gained solid is carried out 1H NMR test, and its spectrogram is as Figure 4 As shown, NMR data: 1 H NMR (400MHz, DMSO-d 6 )δ9.83(s,1H),8.81(d,J=6.7Hz,1H),8.58(d,J=7.6Hz,...

Embodiment 2

[0174] Embodiment 2: the preparation of crystal form CM-I

[0175]Weigh 9mg of the compound of formula (I), dissolve it in 0.4mL formic acid / water (4:1, v / v) at room temperature, and filter. The filtrate was added dropwise to 4 mL of water at 28 °C, stirred for 2 h, and filtered. The solid was dried under vacuum at 25°C for 24 hours, and the obtained solid was the crystal form CM-I of the compound of formula (I). The obtained solid was tested by XRPD, and its X-ray powder diffraction data are shown in Table 2.

Abstract

The invention provides a novel crystal form of (7S, 13R)-11 fluoro-7, 14-dimethyl-6, 7, 13, 14-tetrahydro-1, 15-ethylene bridge pyrazolo [4, 3-f] [1, 4, 8, 10]-benzoxazacyclotridecyne-4 (5H)-one (formula I), and on the other hand, the invention provides a preparation method of the crystal form. Compared with the prior art, the crystal form prepared by the invention is high in stability, low in hygroscopicity, simple and convenient in preparation method, good in solubility and suitable for subsequent preparation research and development and industrial production.

Description

technical field [0001] The present invention relates to the field of medicinal chemistry, in particular to (7S,13R)-11fluoro-7,14-dimethyl-6,7,13,14-tetrahydro-1,15-vinylpyrazolo[4,3 - A new crystal form of f][1,4,8,10]-benzoxatriazacyclotridecyn-4(5H)-one and a preparation method thereof. Background technique [0002] Lapratinib (TPX-0005) is a potent small molecule multi-target kinase inhibitor that was shown to antagonize wild-type and mutant ALA (anaplastic lymphoma kinase), wild-type and mutant ROS1 (pro-ROS1 Oncogene receptor tyrosine kinases), TRK family kinases (tropomyosin-related receptor tyrosine kinases), JAK2 of Janus family kinases, SRC (Src family protein tyrosine kinases (SFK)) and FAK (adhesion Kinase) activity. It is the fourth-generation ALK inhibitor developed by TP Therapeutics. On June 28, 2017, TP Therapeutics announced that the FDA has granted orphan drug designation to its new clinical drug compound TPX-0005 for the treatment of NSCLC (non-small c...
