実験手順

To a suitable vessel were charged amorphous irinotecan acetate (14.5 g) and ethanol (101 mL). The resulting mixture was heated to reflux and remained as a suspension. 2N HCl (10 mL) was added to the reaction mixture to adjust the pH to less than 4. Ethyl Acetate (145 mL) was added to the resulting mixture. The mixture was then cooled to 0˜10° C. and stirred at this temperature for 1 hour, filtrated, and washed with ethyl acetate (100 mL). The solid was then dried in vacuum. Due to a lower than expected water content, the solid was put under atmosphere overnight to give irinotecan hydrochloride trihydrate Form II (13.5 g).
