Procedure

To a solution of 5-carboxymethyl-7-chloro-1-(4-cyclohexylbenzoyl)-2,3,4,5-tetrahydro-1H-benzazepine (0.7 g) in dichloromethane (50 ml) is added with stirring N,N-bis(2-oxo-3-oxazolidinyl)phosphinic chloride (0.54 g) under ice-cooling, and the mixture is stirred at room temperature for 15 minutes. To the mixture are added with stirring N-methylpiperazine (0.24 ml) and triethylamine (0.46 ml) under ice-cooling, and the mixture is stirred at room temperature overnight. To the reaction solution is added water, and the mixture is extracted with dichloromethane. The extract is washed with water, dried over magnesium sulfate, and evaporated to remove the solvent. The residue is purified by silica gel column chromatography (solvent; dichloromethane: methanol=40:1) to give 7-chloro-5-[(4-methyl-1-piperazinyl)carbonylmethyl]-1-(4-cyclohexylbenzoyl)-2,3,4,5-tetrahydro-1H-benzazepine (0.7 g) as colorless amorphous.
