Reaktionsschritte
Triethylamine (0.05 g, 0.5 mmol) was added to a solution of 1a (0.228 g, 1 mmol) and 9a (0.214 g, 1 mmol) in dry THF (2 ml). The reaction mixture was stirred at room temperature for 2 days and then concentrated to yield a dark residue which was subjected to flash chromatography (dichloromethane/acetone, 95:5) to afford 4-(4-imino-2-thioxo-1-(4-methylphenyl)-1,3-diazaspiro[4.5]dec-3-yl)-2-trifluoromethylbenzonitrile, 9b (0.035 g, 0.08 mmol, 8%).
