Reaction Steps

A mixture of ethyl 7-fluoro-2-(trifluoromethyl)-2H-chromene-3-carboxylate (Example 612a, Step 2) (0.45 g, 1.54 mmole) and 3,3-dimethylbutylamine (0.13 g, 1.54 mmole) was dissolved in anhydrous DMF (5 mL), warmed to 90° C. and treated with K2CO3 (0.25 g, 1.84 mmole). The mixture was maintained at 90° C. for 24 hrs, cooled to room temperature, filtered through celite and condensed to a viscous oil (0.55g, 98%). No further purification was performed. LCMS m/z 358.00 (M+H).
