Participants

Reaction Steps

A mixed solution of 5-(2-chloroacetylamino)-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.6 g), imidazole (0.1 g) and potassium carbonate (0.19 g) in acetonitrile (30 ml) is refluxed for 8 hours. The reaction solution is concentrated and the resulting residue is washed with water and separated by decantation. The remainder is purified by silica gel column chromatography (eluent; dichloromethane:methanol=20:1→15:1), and recrystallized from ethanol/n-hexane to give 5-[2-(1-imidazolyl)acetylamino]-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.15 g) as colorless needles, m.p. 250°-252° C.
