Procedure

To a solution of 7-chloro-5-methylidene-1-[6-(2-methylbenzoylamino)nicotinoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.28 g) in t-butanol (3 ml), pyridine (0.2 ml) and water (1.2 ml) is added 4% aqueous osmium tetraoxide solution (0.2 ml), and further thereto is added 4-methylmorpholine N-oxide (0.1 g). The mixture is refluxed for 5 hours, and cooled. Saturated aqueous sodium hydrogen sulfite solution is added to the reaction mixture, and the mixture is stirred at room temperature for 30 minutes. Water is added to the reaction solution, and the mixture is extracted with a mixture of ethyl acetate and tetrahydrofuran. 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-hydroxymethyl-5-hydroxy-1-[6-(2-methylbenzoylamino)nicotinoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.14 g) as colorless amorphous.
