Participants

Reaction Steps

To a mixture solution of 2-(3-bromo-phenyl)-6-chloro-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-8-carboxylic acid methyl ester (1.0 g, 2.5 mmol), 4-tert-butylphenylboronic acid (582 mg, 3.3 mmol) and tetrakis(triphenylphosphine)palladium(0) (289 mg, 0.25 mmol) in dioxane (5.0 mL) was added 2 M sodium carbonate solution in water (2.5 mL). The resulting mixture was subjected to microwave irradiation for 2 h at 110° C. The mixture was diluted with ethyl acetate (200 mL), washed with saturated aqueous sodium bicarbonate solution (50 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′-tert-butyl-biphenyl-3-yl)-6-chloro-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-8-carboxylic acid methyl ester (924 mg, 80%) as a white solid: LC/MS m/e calcd for C29H32ClNO2 (M+H)+: 463.04, observed: 463.1.
