Procedure

A mixture of 4-[3-(4-aminophenyl)-4,4-dimethyl-5-oxo-2-thioxoimidazolidin-1-yl]-2-trifluoromethylbenzonitrile (2d) [RD9] (0.008 g, 0.02 mmol), acetyl chloride (0.004 g, 0.03 mmol) and triethylamine (0.003 g, 0.03 mmol) in dichloromethane (1 ml) was stirred at 0° C. for 2 hours. The mixture was concentrated and chromatographed (dichloromethane:acetone, 90:10) to yield N -{4-[3-(4-cyano-3-trifluoromethylphenyl)-5,5-dimethyl-4-oxo-2-thioxo-imidazolidin-1-yl]phenyl}acetamide, 48a, [RD151] (0.007 g, 0.016 mmol, 80%), the structure of which is illustrated in Formula 3, as a white powder.
