Reaction Steps
Microwave vial was charged with 3-(2-chloro-6-trifluoromethyl-pyridin-3-yl)-acrylic acid ethyl ester (100 mg, 0.376 mmol), phenylboronic acid (2 eq), Cs2CO3 (3 eq), Pd(PPh3)2Cl2 (0.08 eq), DME (1 ml), and ethanol (0.25 ml). The vial was irradiated in microwave synthesizer at 140° C. for 20 min. The contents of the vial were filtered through a celite pad, which was washed out thoroughly with methanol. The filtrate was evaporated, and the residue was purified by column chromatography to give 3-(2-phenyl-6-trifluoromethyl-pyridin-3-yl)-acrylic acid ethyl ester (96 mg, 80%).
