Procedure
To a solution of 7-chloro-1-[6-(2-carboxymethoxybenzoylamino)-nicotinoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.4 g) in dichloromethane (10 ml) is added with stirring N,N-bis(2-oxo-3-oxazolidinyl)phosphinic chloride (0.25 g) under ice-cooling, and the mixture is stirred at room temperature for 15 minutes. Subsequently, to the reaction mixture is added N-methylpiperazine (0.11 ml), and thereto is added triethylamine (0.23 ml). The mixture is stirred at room temperature overnight, and thereto is added water. The mixture is extracted with dichloromethane, and the extract is washed successively with diluted aqueous sodium hydroxide solution and water, dried over magnesium sulfate, and evaporated under reduced pressure to remove the solvent. The residue is purified by silica gel column chromatography, and recrystallized from dichloromethane-diethyl ether to give 7-chloro-1-{6-[2-(4-methyl-1-piperazinyl)-carbonyl methoxybenzoylamino]nicotinoyl}-2,3,4,5-tetrahydro-1H-benzazepine (390 mg) as white powder.
