反応手順
Triethylamine (0.101 g, 1 mmol) was added to a solution of 1a (0.456 g, 2 mmol) and 3a (0.352 g, 2 mmol) in dry THF (5 ml). The reaction mixture was stirred at 0° C. for 48 h and then concentrated to yield a dark residue which was subjected to flash chromatography (dichloromethane/acetone, 85:15) to afford 4-[3-(4-hydroxyphenyl)-5-imino-4,4-dimethyl-2-thioxoimidazolidin-1-yl]-2-trifluoromethylbenzonitrile, 3b (0.274 g, 0.68 mmol, 34%).
