실험 절차

3-(1-Acetyl-4-piperidinyl)propionic acid (10.0 g) was added by portions to thionyl chloride (30 ml) at room temperature. After stirring at room temperature for 30 minutes, thionyl chloride was evaporated under reduced pressure to give the crude product of 3-(1-acetyl-4-piperidinyl)propionyl chloride. Aluminum chloride (20 g) was added by portions to a suspension of the crude product and 2,2,2-trifluoro-N-(2-methoxyphenyl)acetamide (10.0 g) at room temperature. After stirring at room temperature for 1 hour, the reaction mixture was poured into ice (200 g), extracted with ethyl acetate, and washed with brine. The organic layer was dried over anhydrous magnesium sulfate, the solvent was evaporated under reduced pressure, the resulting residue was purified by silica gel chromatography (eluting solvent; ethyl acetate), and the solvent was evaporated to give the title compound as colorless crystals (8.83 g) having a melting point of 77 to 79° C.
