Procedure
Into a solution of 7-(4-methylphenyl)-2,3,4,5-tetrahydro-1-benzooxepine-4-carboxylic acid (141 mg) and 4-[N-methyl-N-(tetrahydropyran-4-yl)aminomethyl]aniline (110 mg) in DMF (4 ml) were added under ice cooling diethyl cyanophosphonate (0.08 ml) and triethylamine (0.08 ml). After being stirred at 0° C. for 30 minutes and at room temperature for 8 hours, an aqueous solution of sodium bicarbonate was added into the reaction mixture under ice cooling. The resulting mixture was extracted with ethyl acetate, and the extract was washed with an aqueous saturated solution of sodium chloride. The extract was dried with anhydrous magnesium sulfate and was then concentrated under reduced pressure. The residue was subjected to purification using silica gel column chromatography (ethyl acetate/hexane=4/1) and further to recrystallization from ethyl acetate/hexane to obtain N-[4-[(N-methyl-N-(tetrahydropyran-4-yl)aminomethyl)phenyl]-7-(4-methylphenyl)-2,3,4,5-tetrahydro-1-benzooxepine-4-carboxamide (compound 25) (43 mg) as colorless crystals.
