Reaction Steps

To a suspension of +[N-[(2,2-dioxido-1,2,3-benzoxathiazin-6-yl)methyl]-N-(1H-imidazol-1-yl)amino]benzonitrile (0.40 g, 1.05 mmol) in methanol (8 ml) was added portionwise NaBH4 (0.08 g, 2.11 mmol) and the reaction mixture was stirred at room temperature for 3 h. After addition of a saturated solution of NH4Cl (3 ml) and water (40 ml), the precipitate obtained was filtered, washed with water and dried to give a white solid. Crystallization from ethyl acetate with ethanol yielded the expected product (0.40 g, 82%, mp: 190° C.).
