実験手順
To a solution of 7-(4-methylphenyl)-2,3-dihydrobenzoxepine-4-carboxylic acid (280 mg) and 2-[(4-aminophenyl)methylamino]pyridine (199 mg) in DMF (4 ml) was added, under ice-cooling, diethyl cyanophosphate (0.18 ml) and triethylamine (0.17 ml), and the mixture was stirred at 0° C. for 30 minutes and then at room temperature for 1 hour. To the mixture was added DMAP (1 piece), and the mixture was stirred at room temperature for 18 hours. Under ice-cooling, to the mixture was added sodium bicarbonate solution, and the mixture was extracted with ethyl acetate, washed with brine, dried (anhydrous magnesium sulfate) and concentrated. The residue was purified with silica gel column chromatography (ethyl acetate/hexane=1/1) and recrystallized from ethyl acetate/hexane to give N-[4-[(pyrid-2-yl)aminomethyl]phenyl]-7-(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (Compound 72) (97 mg) as colorless crystals.
