Reaction Steps

To a mixture of 2-(3-bromo-phenyl)-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (720 mg, 2.0 mmol), 4-(methanesulfonyl)phenylboronic acid (600 mg, 3.0 mmol) and tetrakis(triphenylphosphine)palladium(0) (347 mg, 0.3 mmol) in dioxane (6 mL) was added 2 M sodium carbonate solution in water (4 mL, 8 mmol). The resulting mixture was subjected to microwave irradiation for 60 min at 110° C. The mixture was diluted with ethyl acetate (150 mL), washed with saturated aqueous sodium bicarbonate solution (30 mL×2), brine, dried over anhydrous sodium sulfate and then concentrated in vacuo. Purification by flash silica gel chromatography (silica gel from QingDao, 200-300 mesh, glass column from Shanghai SD company) (10% ethyl acetate/hexanes) afforded 2-(4′-methanesulfonyl-biphenyl-3-yl)-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (696 mg, 80%) as a white solid: LC/MS m/e calcd for C25H25NO4S (M+H)+: 436.55, observed: 436.1.
