Embodiment 1
[0116] 5.1. Example 1: Cyclopropanecarboxylic acid {2-[(1S)-1-(3-ethoxy-4-methoxy-phenyl)-2-methane-sulfonyl-ethyl]-3- Synthesis of oxo-2,3-dihydro-1H-isoindol-4-yl}-amide
[0117] Preparation of methyl 2-methyl-6-nitrobenzoate
[0118] 2-Methyl-6-nitrobenzoic acid (300.0 g, 1.66 mol, from Acros Organics, Morris Plains, NJ) and trimethyl orthoacetate (298.3 g, 2.48 mol, from Aldrich Chemicals, Milwauke, WI) were The mixture was charged to a 3-liter three-necked flask at about 20-25°C under nitrogen. The reaction mixture is gradually heated to distill off the low-boiling components produced in the reaction to an internal temperature of 95-100°C. After 2 hours, the reaction mixture was allowed to cool to 20-25°C over 1-2 hours. After heptane (1.50 L, from Aldrich Chemicals) was charged to the reaction mixture over 1.0-1.5 hours, methyl 2-methyl-6-nitrobenzoate (0.5 g) was inoculated when the reaction mixture became cloudy. The suspension was cooled to 0-5°C within 0.5-1 hour...
Embodiment 2
[0131] 5.2. Example 2: Hot melt extrusion formulation 1
[0132] Formulation 1, a solid powder dispersion of Compound A was prepared as follows:
[0133] 1. use Mixer blends Compound A with HPMC for 460 turns;
[0134] 2. Process the blended compound A at 190°C by hot melt extrusion;
[0135] 3. Use a 18-mesh sieve to grind the extruded product;
[0136] 4. Blend the ground extrudate with pre-screened (35 mesh) croscarmellose sodium and mannitol M200 for 460 rpm;
[0137] 5. Blend the resulting product with pre-screened calcium stearate for 75 revolutions; and
[0138] 6. Capsule the blended product using a semi-automatic encapsulator.
[0139] The above procedure resulted in a physically stable solid dispersion of Compound A with a water solubility of approximately 2 μg / mL.
[0140] Preparation 1
[0141] In other formulations, alternative HPMC products can be used in place of HPMC E3. Schematic diagram for the preparation of hot-melt extruded capsules in f...
Embodiment 3
[0142] 5.3. Example 3: Hot melt extrusion formulation 2
[0143] Preparation 2 is prepared according to the method of Example 2:
[0144] Preparation 2
[0145] Mannitol M200
[0146] In other formulations, alternative HPMC products can be used in place of HPMC E3.
