PROCEDURE

实验过程

To a solution of 4-Methyl-2-(5-trifluoromethanesulfonyloxy-4′-trifluoromethyl-biphenyl-3-yl)-pentanoic acid ethyl ester, compound 1g (105 mg, 0.205 mmol) in dimethoxyethane (1.4 mL), was added 2-pyridine boronic acid pinacol ester adduct (169 mg, 0.41 mmol), and 2M Na2CO3 (0.31 ml, 0.614 mmol). The mixture was degassed, tetrakis(triphenylphosphine)palladium (0) (24.0 mg, 0.02 mmol) was added and the mixture was degassed again, and then heated to 80° C. overnight. The reaction was cooled to room temperature, diluted with EtOAc and washed with NaHCO3 and brine. Purification by column chromatography gave the title compound (30 mg, 33%). Calcd for C26H26F3NO2 (M+H) 441.49, Found 442.2.
