A microwave vial is charged with 3-[6-(4-chloro-3-trifluoromethyl-phenoxymethyl)-3,4-dihydro-1H-isoquinolin-2-yl]-propionic acid tert-butyl ester (56 mg, 0.119 mmol), phenylboronic acid (17 mg, 1.2 eq.), Pd(OAc)2 (1.3 mg, 5 mol %), (dicyclohexylphosphino)biphenyl (4.2 mg, 10 mol %), KF (21 mg, 3 eq.), and THF (0.25 mL). The resulting mixture is heated to 120° C. using microwave irradiation for 20 minutes. The mixture is filtered through celite. The celite is washed with EtOAc several times. The filtrate is then concentrated to give a dark oil. The mixture is purified by column chromatography (silica gel, EtOAc/Hexane, gradient) to give 3-[6-(2-trifluoromethyl-biphenyl-4-yloxymethyl)-3,4-dihydro-1H-isoquinolin-2-yl]-propionic acid tert-butyl ester.
