실험 절차

Methanesulfonic acid (1.3 ml, dissolved in 11 ml of absolute ethanol) is slowly added to a solution of Donepezil (3.79 g) in absolute ethanol (38 ml) with stirring at room temperature, and 50 ml of dipropyl ether is added. The solid precipitated is filtered and dried at 55° C. under vacuum to give the title compound. Melting point: 180.3° C.
