Reaktionsschritte

A solution of N-(3-methylbutyl)thiourea (3.00 g, 20.5 mmol), 2-bromo-1-[4-(trifluoromethyl)phenyl]ethanone (5.45 g, 20.5 mmol) and sodium acetate (2.19 g, 26.7 mmol) in ethanol (50 mL) was stirred at 90° C. for 4 hr. The reaction mixture was poured into water, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The obtained solid was recrystallized from dichloromethane-hexane to give the title compound (1.76 g, yield 27%) as pale-yellow crystals.
