実験手順

To a 100 mL reactor was charged amorphous irinotecan acetate (2.0 g) and methanol (14 mL). The reaction mixture was heated to 50° C. 2N hydrochloric acid (6.2 wt %, about 1.7 mL) was added to adjust the pH level to less than 4 in order to dissolve the solid particles. Ethyl acetate (40 mL) was added slowly to the mixture. The mixture was cooled to 0˜10° C. and stirred at this temperature for 1 hour. The solid particles were filtered and washed with cooled ethyl acetate (6 mL). The wet cake was dried in vacuum to give 1.66 g of irinotecan hydrochloride trihydrate Form III.
