反応手順
Triethylamine (0.101 g, 1 mmol) was added to a solution of 1a (0.456 g, 2 mmol) and 5a (0.348 g, 2 mmol) in dry THF (3 ml). The reaction mixture was stirred at 0° C. for 2 days and then concentrated to yield a dark residue which was subjected to flash chromatography (dichloromethane/acetone, 95:5) to afford 4-[3-(4-methylphenyl)-5-imino-4,4-dimethyl-2-thioxoimidazolidin-1-yl]-2-trifluoromethylbenzonitrile, 5b (0.136 g, 0.34 mmol, 17%).
