Reaction Steps

Piperidine-4-carboxylic acid [4-(3-dimethylaminopyrrolidin-1-yl)phenyl]amide (70 mg) dissolved in N-methylpyrrolidone (2 ml) was mixed with potassium carbonate (45 mg) and 4-fluorobenzenesulfonyl chloride (40 mg). After 12 hours, the mixture was filtered and the filtrate was purified by preparative HPLC. This resulted in the product with the molecular weight of 474.60 (C24H31FN4O3S); MS (ESI): 475 (M+H+).
