Conditions

Temperature: 110 °C

Procedure

To a solution of 7-chloro-1-{6-[2-(2-methanesulfonyloxyethoxy)benzoylamino]nicotinoyl}-2,3,4,5-tetrahydro-1H-benzazepine (0.75 g) in dimethylformamide (10 ml) is added potassium phthalimide (0.26 g), and the mixture is stirred at 110° C. for one hour. The mixture is poured into ice-water, and extracted with dichloromethane. The extract is washed with water, dried over magnesium sulfate, and evaporated under reduced pressure. The residue is purified by silica gel column chromatography to give 7-chloro-1-[6-(6,7-benzo-1-oxo-4-azepin-5-on-4-yl)nicotinoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.23 g, Compound A) and 7-chloro-1-{6-[2-(2-phthalimidoethoxy)benzoylamino]nicotinoyl}-2,3,4,5-tetrahydro-1H-benzazepine (0.25 g, Compound B), separately.
