Procedure

The mixture of 2-sulfamoylamino-6-(methylthio)benzonitrile (Example 104a) (48 mg, 0.2 mmol) and MCPBA (69 mg, 0.4 mmol) in dichloromethane (16 mL) was heated refluxed overnight. After cooling down, the precipitation was collected by filtration, rinsed with dichloromethane, dried in the air to give the title compound. 1H NMR (400 MHz, DMSO-d6) δ 2.83 (s, 3H), 7.35 (brs, 2H), 7.72-6.69 (m, 2H), 7.92 (t, J=8.0 Hz, 1H), 9.87 (brs, 1H).
