Reaction Steps

A mixture of 4-[3-(4-aminophenyl)-4,4-dimethyl-5-oxo-2-thioxoimidazolidin-1-yl]-2-trifluoromethylbenzonitrile (2d) (0.02 g, 0.05 mmol), methanesulfonyl chloride (0.009g, 0.075 mmol) and pyridine (0.006 g, 0.075 mmol) in dichloromethane (1 ml) was stirred at room temperature for 15 hours. The medium was washed with water (2 ml) and extracted with ethyl acetate (5 ml). The organic layer was dried over MgSO4, concentrated and chromatographed (HPLC, alumina column) to yield N-{4-[3-(4-cyano-3-trifluoromethylphenyl)-5,5-dimethyl-4-oxo-2-thioxo-imidazolidin-1-yl]phenyl}methanesulfonamide (47a) [RD150] (0.009 g, 0.018 mmol, 36%), the structure of which is illustrated in Formula 2, as a white powder.
