Reaction Steps

5-Methyl-3-(3-trifluoromethyl-phenyl)-imidazo[1,2-a]pyridin-2-ylamine (compound s, 0.05 g, 0.0002 mol) was dissolved in acetonitrile (0.9 mL) and pyridine (0.03 mL, 0.0003 mol). t-butylacetyl chloride (0.028 mL, 0.00020 mol) was added and the mixture was stirred at room temperature for 4 hours. Solvent was removed then ethyl acetate and saturated sodium bicarbonate was added. The layers were separated and the organic layer dried (magnesium sulfate) then removed. The crude product was chromatographed using 60% ethyl acetate/hexanes to give 39 mg of 3,3-Dimethyl-N-[5-methyl-3-(3-trifluoromethyl-phenyl)-imidazo[1,2-a]pyridin-2-yl]-butyramide as a white solid. Rf 0.27, 100% ethyl acetate; MS m/z 390 (M+H). SH-SY5Y_EC50: 0.3399.
