Procedure

A suspension of N-(4-chloromethylphenyl)-7—(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (0.1 g), benzylamine hydrochloride (0.5 g) and potassium carbonate (0.6 g) in dimethylformamide (10 ml) was stirred at room temperature over night. 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 (ethyl acetate/methanol/triethylamine) to give crude crystals, which were recrystallized from ethyl acetate-hexane to give N-(4—((benzylamino)methyl)phenyl)-7—(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (Compound 117) (0.08 g) as colorless crystals.
