Reaction Steps

A mixture of ethyl 6-chloro-7-fluoro-2-(trifluoromethyl)-2H-chromene-3-carboxylate (Example 7a, Step 2) (0.5 g, 1.54 mmole) and 3,3-dimethylbutylamine (0.11 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 (0.58 g, 98%). No further purification was performed: GCMS m/z 377.00 (M+).
