Procedure

To a solution of compound 33b, 4-Methyl-2-(5-piperidin-3-yl-4′-trifluoromethyl-biphenyl-3-yl)-pentanoic acid ethyl ester (44.4 mg, 0.10 mmol) in CH3CN (5 ml) was added 2-Bromomethyl napthalene) (33 mg, 0.15 mmol) and diisopropylethylamine (35 μl, 0.20 mmol). The reaction was microwaved at 130° C. for 10 minutes, then diluted with EtOAc and washed with brine, sat. NaHCO3, and brine, dried and filtered. Purification by silica gel chromatography (Isco) gave the desired product as a clear oil, (51 mg, 87%). Calcd for C37H40F3NO2 (M+H) 587.71, Found 588.5.
