Reaction Steps

Sodium hydride (0.43 g, 0.018 mol) was mixed with N,N-Dimethylformamide (67.4 mL) and N-(5-fluoropyridin-2-yl)-4-methylbenzenesulfonamide 1 (4.0 g, 0.015 mol) was added. The reaction was stirred at room temperature for 10 minutes. Iodoacetamide (3.3 g, 0.018 mol) was added and the mixture was stirred at room temperature for 24 hours. The reaction was poured into water (100 mL) and extracted with ethyl acetate (4×75 mL). Organic layers were combined then dried with magnesium sulfate and the solvent removed. The crude product was chromatographed on silica using 5% methanol in dichloromethane to give 2-(5-fluoro-2-(tosylimino)pyridin-1(2H)-yl)acetamide 2 Rf 0.26, 5% methanol.dichloromethane; MS m/z 324 (M+H)
