Sodium hydride (0.040 g, 0.0017 mol) was suspended in N,N-dimethylformamide (15 mL) and was cooled at 0° C. N-(5-fluoropyridin-2-yl)-4-methylbenzenesulfonamide (compound a, 0.37 g, 0.0014 mol) was added and was stirred for 15 minutes. 2-Bromo-2-phenylacetamide h (0.3 g, 0.001 mol) was added then the reaction was warmed to room temperature and was stirred for 24 hours. The reaction was poured into water and extracted with ethyl acetate (3×50 mL) then dried then chromatographed on silica (50% ethyl acetate/hexanes) to give 2-(5-fluoro-2-(tosylimino)pyridin-1(2H)-yl)-2-phenylacetamide (compound j) Rf 0.42, 50% ethyl acetate/hexanes; MS m/z 400 (M+H).
