Reaction Steps

A 20 mL vial is charged with 5-(6-chloroimidazo[1,2-a]pyridin-2-yl)-2-(trifluoromethyl)aniline (0.156 g, 0.5 mmol), acetonitrile (4.12 mL) and pyridine (0.081 mL). The mixture is added trimethylacetyl chloride (0.123 mL, 0.001 mol) and stirred for 20 min at 80° C. The solution is concentrated, taken into EtOAc (10 mL) and washed once with HCl (10 mL, 1M) and NaOH (10 mL, 1M). Organics are dried, concentrated purified on silica (0-100% EtOAc in Hexanes) to give the title compound (106 mg, 54% yield). LCMS m/z=396.4 [M+H]+, tR=2.54 min. (compound same as Example 81)
