Tert-butyl acetyl chloride (0.040 mL, 0.00029 mol) was added to a solution of 3-Cyclopropyl-6-fluoro-imidazo[1,2-a]pyridin-2-ylamine (compound f, 0.054 g, 0.00027 mol) in acetonitrile (5.00 mL) containing pyridine (0.0637 g, 0.00081 mol) and the mixture stirred at room temperature for 1 hour. The reaction mixture was concentrated in vacuo and crude product purified by column chromatography (50% ethyl acetate/hexanes to neat ethyl acetate) to give N-(3-cyclopropyl-6-fluoro-imidazo[1,2-a]pyridin-2-yl)-3,3-dimethyl-butyramide as a yellow solid. Rf 0.41, 5% methanol/dichloromethane; MS m/z 289 (M+H). SH-SY5Y_EC50 (μM): 2.5464.
