2-bromo-2-phenylacetamide

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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). the reaction was warmed to room temperature was stirred for 24 hours extracted with ethyl acetate (3×50 mL) then dried then chromatographed on silica (50% ethyl acetate/hexanes)

Procedure: Benzeneacetamide (3.0 g, 0.022 mol) was dissolved in dichloromethane (60 mL) and N-bromosuccinimide (4.0 g, 0.022 mol) was added. The reaction was stirred at room temperature under UV light for 24 hr. The mixture was poured into water and the layers were separated. The organic layer was washed with water (2×50 mL) then with brine (1×50 mL). The organic layer was dried (magnesium sulfate) then chromatographed on silica (40% ethyl acetate/hexanes) to give 2-Bromo-2-phenylacetamide, compound h Rf 0.37, 40% ethyl acetate/hexanes; MS m/z 216 (M+H). the layers were separated The organic layer was washed with water (2×50 mL) The organic layer was dried (magnesium sulfate) then chromatographed on silica (40% ethyl acetate/hexanes)
