Procedure

To a stirred solution of 100 mg of 5-{4-(aminosulfonyl)phenyl}-2,2-dimethyl-4-iodo-3(2H)-furanone dissolved in 15 ml toluene and 5 ml ethanol, were added 30 mg of tetrakis(triphenylphosphine)palladium(0), 5 ml of 2 M aqueous sodium carbonate, and 100 mg of 3-(trifluoromethyl)benzeneboronic acid. Then the mixture was stirred at 95° C. for 24 hours. The reaction mixture was purified according to a procedure similar to Step 4 of Example 22 to yield 35 mg of 5-{4-(aminosulfonyl)phenyl}2,2-dimethyl-4-{3-(trifluoromethyl)phenyl}-3(2H)-furanone. mp: 129-130° C. NMR: δ1.59 (s, 6H), 4.93 (br, s, 2H), 7.48 (m, 2H), 7.59 (m, 2H), 7.76 (d, J=8.7 Hz, 2H), 7.93 (d, J=9.0 Hz, 2H). IR (cm−1): 3343, 3265, 1691, 1593, 1329, 1262.
