Procedure

To 8.5 mL of degassed ethylene glycol dimethyl ether, was added 500 mg (0.85 mmol) of the ester, 110 mg (0.93 mmol) of phenylboronic acid, 80 mg (0.07 mmol) of tetrakis(triphenylphosphine)palladium and 1.1 ml (2.2 mmol) of 2M aqueous Na2CO3 and the mixture ws heated to reflux under nitrogen for 36 hr. The reaction was cooled to room temperature, diluted with ethyl acetate, washed with water and brine, dried over MgSO4, filtered and concentrated in vacuo to give 4-[(biphenyl-4-sulfonyl)-pyridin-3-ylmethyl-amino]-7-trifluoromethyl-quinoline-3-carboxylic acid ethyl ester.
