Procedure

Into a suspension of 7-(4-methylphenyl)-2,3-dihydro-1-benzooxepine-4-carboxylic acid (400 mg) and 1-hydroxybenzotriazole (289 mg) in acetonitrile (20 ml) was added at room temperature 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.41 g), and the resulting mixture was stirred for 2 hours. Into the reaction mixture was added a solution of tert-butyl trans-4-[N-(4-aminocyclohexylmethyl)-N-methylamino]piperidine-1-carboxylate (698 mg) and triethylamine (0.4 ml) in acetonitrile (30 ml), and the resulting mixture was stirred for 20 hours. After the reaction mixture was concentrated under reduced pressure, water was added to the residue, and the resulting mixture was extracted with ethyl acetate. The organic layer was washed with an aqueous saturated solution of sodium chloride and was dried with magnesium sulfate. After the resulting organic layer was concentrated under reduced pressure to remove the solvent, the residue was subjected to purification using column chromatography (ethanol/ethyl acetate 1:3→1:2) and to recrystallization (ethyl acetate/hexane) to obtain trans-N-[4-[N-(1-tert-butoxycarbonylpiperidin-4-yl)-N-methylaminomethyl]cyclohexyl]-7-(4-methylphenyl)-2,3-dihydro-1-benzooxepine-4-carboxamide (compound 65) (560 mg) as colorless crystals.
