反応手順
To a solution of Flecainide free base (1.5 g) in isopropanol (7.5 ml) was added glacial acetic acid (0.3 g) and the solution was stirred under reflux for 2 hours. The solution was cooled to room temperature and hexane (15 ml) was added and solids began to precipitate. The resulting suspension was stirred at 20–25° C. for 2 hours and the solids were filtered and then rinsed with hexane (2×10 ml). The damp cake was dried in vacuum for 4 hours to give Flecainide acetate as a white solid (1.54 g, Yield 89%).
