Reaction Steps

To a solution of 7-chloro-1-{6-[2-(2-phthalimidoethoxy)benzoylamino]nicotinoyl}-2,3,4,5-tetrahydro-1H-benzazepine (0.25 g) in ethanol (5 ml) is added hydrazine monohydrate (0.03 ml), and the mixture is refluxed for one hour, and cooled. To the mixture is added water, and the mixture is made acidic with diluted hydrochloric acid, and washed with diethyl ether. The aqueous layer is made basic with aqueous sodium hydroxide solution, and extracted with dichloromethane. The extract is washed with water, dried over magnesium sulfate, and evaporated under reduced pressure to remove the solvent. The residue is crystallized from diethyl ether to give 7-chloro-1-{6-[2-(2-aminoethoxy)benzoylamino]nicotinoyl}-2,3,4,5-tetrahydro-1H-benzazepine (110 mg) as white powder.
