Procedure

Into a suspension of 7-(4-methylphenyl)-2,3-dihydrobenzooxepine-4-carboxylic acid (200 mg) and 1-hydroxybenzotriazole (145 mg) in acetonitrile (10 ml) was added at room temperature 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (205 mg), and the resulting mixture was stirred for 2 hours. To the reaction mixture was added a solution of trans-4-[N-methyl-N-(tetrahydropyran-4-yl)aminomethyl]cyclohexylamine dihydrochloride (320 mg), 1,8-diazabicyclo[5,4,0]-7-undecene (326 mg) and triethylamine (0.2 ml) in acetonitrile (10 ml), and the resulting mixture was stirred for 4 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 under reduced pressure to remove the solvent and the residue was then subjected to purification using column chromatography (ethanol/ethyl acetate 1:1) and to recrystallization (ethyl acetate/hexane) to obtain trans-7-(4-methylphenyl)-N-[4-[N-methyl-N-(tetrahydropyran-4-yl)aminomethyl]cyclohexyl]-2,3-dihydro-1-benzooxepine-4-carboxamide (compound 63) (233 mg) as colorless crystals.
