Reaction Steps

6-fluoro-3-phenylimidazo[1,2-a]pyridin-2-amine (compound l, 0.075 g, 0.00033 mol) was dissolved in tetrahydrofuran (5.0 mL) and pyridine (29 uL, 0.00036 mol) was added. Rxn cooled to 0° C. and 4-fluorophenylacetyl chloride (48 uL, 0.00036 mol) was added. The reaction was stirred at 0° C. for 30 minutes. The solvent was removed and the crude product was partioned between water (25 mL) and EtOAc (25 mL). The layers were separated and the organic layer was washed 3×20 mL with water. The organic layer was dried (magnesium sulfate) then chromatographed on silica (70% ethyl acetate/hexanes) to give N-(6-fluoro-3-phenylimidazo[1,2-a]pyridin-2-yl)-2-(4-fluorophenyl)acetamide Rf 0.37, 70% ethyl acetate/hexanes; MS m/z 364 (M+H). SH-SY5Y_EC50 (μM): 0.7321.
