Procedure
To a solution of 7-chloro-5-(2-aminoethyl)-1-[6-(2-methylbenzoyl-amino)nicotinoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.42 g) in pyridine (10 ml) is added acetic anhydride (0.13 ml), and the mixture is stirred at 80° C. for 2 hours, and then stirred at room temperature overnight. Water is added to the reaction solution, and the mixture is extracted with dichloromethane. The extract is washed successively with diluted hydrochloric acid, water, and aqueous sodium hydrogen carbonate solution, dried over magnesium sulfate, and evaporated under reduced pressure to remove the solvent. The residue is purified by silica gel column chromatography to give 7-chloro-5-(2-acetylamino-ethyl)-1-[6-(2-methylbenzoylamino)nicotinoyl]-2,3,4,5-tetrahydro-1H-benzazepine (91 mg) as white powder.
