실험 절차

Mix (benzo[b]thiophene-3-yl)(4-piperidinyl)methanone.CF3CO2H (2.0 g, 5.56 mmol), 2-(4-methoxyphenyl)ethyl bromide (1.27 g, 5.93 mmol), potassium carbonate (1.95 g, 1.41 mmol) and anhydrous dimethylformamide (20 mL). Warm to approximately 90° C. and stir overnight. Allow to cool to room temperature and partition between a 2:1 mixture of ethyl acetate:toluene and water. Separate the aqueous phase and wash the organic phase with water and saturated sodium chloride. Dry (Na2SO4) and evaporate the solvent in vacuo. Purify by chromatography (40% ethyl acetate/hexane) and recrystallize (cyclohexane) to give the title compound as pale yellow plates; mp 114°-116° C.
