实验过程

To a solution of 5.0 g of olanzapine base in 150 ml acetone was slowly added a solution of 1.53 g of methane sulfonic acid in 50 ml of acetone at room temperature. The mixture was stirred for 1 hour and then overnight at 4° C. Crystals were isolated by filtration, washed with 10 ml of acetone and 20 ml of ether and dried overnight at 40° C. in vacuo. Yield: 6.62 g (95%) as a hemi-acetonate.
