Into a solution of 7-(4-methylphenyl)-2,3-dihydro-1-benzooxepine-4-carboxylic acid (150 mg) and 1-hydroxybenzotriazole (0.14 g) in acetonitrile (10 ml) was added at room temperature 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (0.20 g), and the resulting mixture was stirred for one hour. Into the reaction mixture was added a solution of 4-amino-1-[2-[N-methyl-N-(tetrahydropyran-4-yl)amino]ethyl]piperidine dihydrochloride (282 mg), triethylamine (0.15 ml.) and diazabicyclo[5,4,0]-7-undecene (0.37 g) in acetonitrile (15 ml), and the resulting mixture was stirred for 18 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. The resulting organic layer was evaporated to remove the solvent, and then the residue was subjected to purification using column chromatography (triethylamine/ethanol/ethyl acetate 1:10:10) and further to recrystallization (ethyl acetate/hexane) to obtain 7-(4-methylphenyl)-N-[1-[2-[N-methyl-N-(tetrahydropyran-4-yl)amino]ethyl]piperidin-4-yl]-2,3-dihydro-1-benzooxepine-4-carboxamide (compound 62) (99 mg) as colorless crystals.
