Procedure

To a solution of 7—(4-methylphenyl)-N-(4-hydroxy-methylphenyl)-2,3-dihydro-1-benzothiepine-4-carboxamide (0.2 g), triethylamine (0.21 ml) and dimethylaminopyridine (catalytic amount) in tetrahydrofuran (10 ml) was dropwise added methane-sulfonylchloride (0.06 ml) under ice-cooling, and the mixture was stirred for 10 minutes. To the mixture was added piperidine (0.15 ml), and the mixture was. stirred at room temperature for 2 hours. The solvent was evaporated, and to the residue was added water. The mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated sodium chloride solution, and dried with anhydrous magnesium sulfate. Under reduced pressure, the solvent was evaporated, and the residue was purified with silica gel column (methanol/triethylaminelethyl acetate) to give crude crystals, which were recrystallized from ethyl acetate-hexane to give 7—(4-methylphenyl)-N-(4-piperidinomethylphenyl)-2,3-dihydro-1-benzothiepine-4-carboxamide (Compound 93) (0.19 g) as colorless crystals.
