Triethylamine (0.202 g, 2 mmol) was added to a solution of 1a (0.456 g, 2 mmol) and 2b (0.57 g, 2 mmol) in dry THF (5 ml). The reaction mixture was stirred at room temperature for 15 h and then concentrated to yield a dark residue which was subjected to flash chromatography (ethyl ether/acetone, 97:3) to afford {4-[3-(4-cyano-3-trifluoromethylphenyl)-4-imino-5,5-dimethyl-2-thioxo-imidazolidin-1-yl]phenyl}carbamic acid tert-butyl ester, (2c) (0.15 g, 0.3 mmol, 15%).
