The title compound was prepared from 6-fluoro-3-(2-thenoyl)-4-azaoxindole (Example 5) according to the procedure of Example 2C, using 6-fluoro-3-(2-thenoyl)-4-azaoxindole (419 mg, 1.60 mmol), N-chlorosulfonyl isocyanate (0.2 mL, 2.3 mmol), and acetonitrile (8 mL). Reaction time: 3 days. The crude N-chlorosulfonyl carboxamide was hydrolysed by stirring in DMSO in a flask open to the air, diluting with water, and collecting the product by filtration. The product was recrystallized from acetic acid. Yield: 210 mg (43%).
