Procedure
To a solution of 7-chloro-1-{6-[2-(2-hydroxyethoxy)benzoylamino]nicotinoyl}-2,3,4,5-tetrahydro-1H-benzazepine (0.5 g )in pyridine (10 ml) is added with stirring methanesulfonyl chloride (0.1 ml) under ice-cooling, and the mixture is stirred at room temperature for 2 hours. To the reaction solution is added water, and the precipitated crystals are collected by filtration, and dissolved in dichloromethane. The mixture is washed successively with diluted hydrochloric acid and water, dried over magnesium sulfate and evaporated under reduced pressure. The residue is crystallized from diethyl ether to give 7-chloro-1-{6-[2-(2-methanesulfonyloxyethoxy)benzoylamino]nicotinoyl}-2,3,4,5-tetrahydro-1H-benzazepine (0.59 g) as white powder.
