実験手順
To a solution of (5R)-5-carboxymethyl-1-[4-(1-pyrrolidinyl)-2-chlorobenzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (21 g) in dimethylformamide (400 ml) are added isopropylamine (21.7 ml) and diethyl cyanophosphate (10 g) at room temperature, and the mixture is stirred at room temperature for two hours. To the reaction solution are added water and ethyl acetate--n-hexane (10:1), and the mixture is extracted twice. The organic layer is washed successively with a 5% citric acid, a saturated aqueous sodium hydrogen carbonate solution, and water, and dried over anhydrous magnesium sulfate. The mixture is concentrated under reduced pressure to remove the solvent, and the resulting residue is purified by silica gel column chromatography (solvent; dichloromethane:methanol:ammonium hydroxide=1000:5:0.2→1000:15:0.5), and recrystallized from acetone--n-hexane to give (5R)-5-isopropylaminocarbonylmethyl-1-[4-(1-pyrrolidinyl)-2-chlorobenzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (12.5 g).
