Reaction Steps
A microwave vial is charged with 2-(4-chloro-3-trifluoromethyl-phenyl)-6-methylbenzothiazole (170 mg, 0.519 mmol), phenylboronic acid (95 mg, 1.5 eq.), KF (90 mg, 3 eq.), Pd(OAc)2 (6 mg, 5 mol %), (dicyclohexylphosphino)biphenyl (18 mg, 10 mol %) and THF (0.5 mL). The mixture is heated to 120° C. for 30 minutes using microwave irradiation. The mixture is then filtered through celite and washed with EtOAc. The filtrate is concentrated and purified by column chromatography (EtOAc/Hexane, 5/95) to give 120 mg (63%) of 6-methyl-2-(2-trifluoromethyl-biphenyl-4-yl)benzothiazole.
