Reaction Steps

To a solution of 7-chloro-5-(2-phthalimidoethoxy)-1-[6-(2-methylbenzoylamino)nicotinoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.26 g) in ethanol (10 ml) is added hydrazine hydrate (0.04 ml), and the mixture is refluxed for 2 hours, and cooled. Water is added to the reaction solution, and the mixture is made acidic with diluted hydrochloric acid, and washed with diethyl ether. Aqueous sodium hydroxide solution is added to the aqueous layer in order to make it basic, and the mixture is 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 purified by silica gel column chromatography to give 7-chloro-5-(2-aminoethoxy)-1-[6-(2-methylbenzoylamino)nicotinoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.26 g) as colorless amorphous.
