Diisopropylethylamine → 4-Methyl-2-{5-[1-(4-pyrrol-1-yl-benzyl)-piperidin-3-yl]-4'-trifluoromethyl-biphenyl-3-yl}-pentanoic acid ethyl ester

Participants

Reaction Steps

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 1-[4-Bromomethyl) phenyl]-H-pyrrole) (35.1 mg, 0.15 mmol) and diisopropylethylamine (35 μl, 0.20 mmol). The reaction was microwaved at 150° C. for 1 hour, then continued at room temperature overnight, 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, (56 mg, 94%). Calcd for C37H41F3N2O2 (M+H) 602.73, Found 603.5
