34% | With hydrogenchloride In water; isopropyl alcohol at 5 - 40℃; | 2 Mono-HCl Salt Form 1 Approximately 3.5 g of Compound C0105 free base was dissolved in about 1 mL of 2-propanol at 40 °C and a solution of 1 equivalent of 37% HC1 (1.128 mL) in 1.9 L of 2-propanol was added to the mixture drop-wise under stirring at 40°C. The resulting mixture was cooled from 40 °C to 5°C at a rate of about l°C/minute. A suspension was obtained and stirred at ambient room temperature for a further 3 hours. The resulting white solid was filtered and dried at ambient conditions prior analysis. About 2.5 g of material was recovered of this new polymorphic form labeled Form 1. Another 0.2 g of solid was obtained from the mother liquors of this preparation by stirring for about 24 hours at 5°C, providing a total yield of 34%. The XRPD spectrum for this solid polymorphic compound is shown in Fig. 6. |

With hydrogenchloride In water; isopropyl alcohol at 2 - 50℃; for 3h; | 2 Dihydrochloride Polymorph Form 2 Mono-Hydrate Approximately 9.6 g of Compound C0105 free base was mixed with 30 mL of 2-propanol. The resulting suspension was stirred at 50°C for about 1 hour, followed by drop-wise addition of an aqueous solution of 37% HC1 (9.3 mL, 3 equivalents) in 10 mL of 2-propanol. A white suspension was obtained that was stirred at 50 °C for about 1 hour, then at ambient room temperature for 1 hour, and finally at about 2°C for 1 hour. The solid material recovered was filtered in vacuo and suspended in a mixture of acetone/water (20% water, 8 mL) . The obtained slurry was temperature cycled between ambient and 40°C, in 4 hour cycles. The resulting solids were filtered and XRPD analysis after drying indicated a new polymorphic form labeled Form 2 dihydrochloride hydrate, whose XRPD spectrum is shown in Fig. 2. |
