They were each treated with 250 ⁇ L of a saturated solution of pattern 1 (ED01748-006-001-00) in either DIPE or heptane (treated with 50 mg of ED01748-006-001-00 in DIPE or heptane, heated at 50, then Remove a portion along and filter through a 0.45 ⁇ m syringe filter to form a slurry). The resulting slurry was stirred at room temperature or 50 °C. A small sample was periodically removed and analyzed by XRPD to monitor progress as shown in the table below.
- Pattern 1 and Pattern 3 (ED01748-028-003-00, 10 mg portion) was weighed into 4 vials, Pattern 6 (ED01748-034-002-00, 5 mg) and Pattern 11 (ED01748-037-002- 00, 5 mg) was added to each vial. They were treated with 300 ⁇ L of filtered saturated solution of pattern 1 (ED01748-006-001-00) prepared in DIPE or heptane, respectively. The resulting slurry was stirred at room temperature and 50°C. A small sample was periodically removed and analyzed by XRPD and monitored as described in the table below.
- the solid was put back into the vial, and additional saturated solution was injected if necessary to maintain the slurry. After 25 days, the purity of the solid material obtained in the heptane experiment was checked by UPLC, and the purity was not significantly lowered by UPLC.
