Procedure

A mixture of 6-bromo-3-phenyl-2,4-bis(trifluoromethyl)quinoline (273 mg, 0.650 mmol, Intermediate 8, step c), CuI (14 mg, 0.074 mmol), N,N′-dimethylethylenediamine (0.0158 mL, 0.147 mmol), t-BuOH (0.65 mL), and NaI (200 mg, 1.33 mmol) was microwaved at 150° C. for 30 min (Biotage). The reaction was diluted with DCM (10 mL), filtered through Celite® and a 0.45 um filter, and concentrated. The residue was flash chromatographed with a heptane to 20% EtOAc/heptane gradient to afford the title compound as a light yellow oil that crystallized upon standing.
