Reaction Steps

o-Cresol (0.36 g) is dissolved in dimethylsulfoxide (4 ml) containing sodium hydroxide powder (0.18 g) and thereto is added 1-[4-(2-chloroacetylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (1.03 g). The mixture is stirred at 90° C. for 7.5 hours. The reaction mixture is poured into ice-water (300 ml) and the precipitated crystal is collected by filtration, washed with water, and purified by silica gel column chromatography (eluent; n-hexane:ethyl acetate=2:1), and recrystallized from ethyl acetate to give 1-{4-[2-(2-methylphenoxy)acetylamino]benzoyl}-2,3,4,5-tetrahydro-1H-benzazepine (546 mg) as colorless scales, m.p. 172.5°-175° C.
