Reaction Steps

To a stirred solution of 0.38 g (1 mmol) of N-(4-amino-phenyl)-2-[4-(4-fluoro-benzyl)-piperidin-1-yl]-acetamide dihydrochloride (Example 181) and 0.28 ml (2 mmol) of triethylamine in 10 ml of dichloromethane 0.1 ml (1 mmol) of acetic anhydride in 2 ml of dichloromethane is added dropwise below 10° C., and the reaction mixture is stirred at room temperature for 3 hours. The solvent is evaporated and the residue is treated with water and the crystals are filtered off to yield 0.15 g (39%) of the title compound. Melting Point: 173-180° C. (water)
