Versuchsvorschrift

4-fluoro-N-methylbenzenesulfonamide (189 mg, 0.999 mmol) and piperazine (430 mg, 4.99 mmol) were combined and the reaction mixture was stirred at 120° C. for 2 h. It was diluted with water (5 mL) and stirred until a fine suspension resulted. The precipitate was filtered, washed with water (5×3 mL) and dried in vacuum to afford N-methyl-4-(piperazin-1-yl)benzenesulfonamide (222 mg, 0.869 mmol, 87% yield) as a white solid. ESI-MS: m/z 256 (M+H)+.
