To a solution of 1-{4-[2-(2-methylphenyl)benzoylamino]benzoyl}-2,3,4,5-tetrahydro-1H-1-benzazepin-5-one (620 mg) in methanol (20 ml) was added sodium borohydride (49.4 mg) and the mixture was stirred at ambient temperature for 4 hours. The mixture was diluted with chloroform and the solution was washed with water and brine, and dried over magnesium sulfate. The solvent was evaporated in vacuo to give a syrup and the residue was purified by silica gel column (30g, 1% methanol in chloroform) to give 5-hydroxy-1-{4-[2-(2-methylphenyl)benzoylamino]benzoyl}-2,3,4,5-tetrahydro-1H-1-benzazepine (580 mg).
