Participants

Conditions

Temperature: 110 °C

Procedure

To a solution of 7-chloro-5-(2-methanesulfonyloxyethoxy)-1-[6-(2-methylbenzoylamino)nicotinoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.55 g) in dimethylformamide (10 ml) is added potassium phthalimide (0.2 g), and the mixture is stirred at 110° C. for one hour. The reaction solution is poured into ice-water, 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-phthalimidoethoxy)-1-[6-(2-methylbenzoylamino)nicotinoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.4 g) as colorless amorphous.
