Procedure

To a solution of 3-[3-(morpholin-4-ylcarbonyl)-5,5-dioxidothiochromeno[4,3-c]pyrazol-1(4H)-yl]benzonitrile (0.3 g, 0.69 mmol) in EtOH (20 mL) is added 50% aq. hydroxylamine solution (0.14 mL, 2.07 mmol). The reaction mass is heated to 85° C. for 12 h. The solvent is removed completely under reduced pressure to afford 150 mg (89%) of the title compound as a white solid. MS (ESI+): 468.0.
