実験手順

Into a 50-mL round bottom flask, was placed 4-[5-[3-chloro-5-(trifluoromethyl)phenyl]-5-(trifluoromethyl)-4,5-dihydro-1,2-oxazol-3-yl]-2-(trifluoromethyl)benzoic acid (50 mg, 0.10 mmol, 1.00 equiv), N,N-dimethylformamide (2 mL), EDCI (38 mg, 0.20 mmol, 2.00 equiv), HOBt (27 mg, 0.20 mmol, 2.02 equiv), TEA (50 mg, 0.49 mmol, 5.00 equiv), imidazolidin-4-one (17 mg, 0.20 mmol, 2.00 equiv). The resulting solution was stirred for 30 min at 25° C. The resulting solution was allowed to react, with stirring, for an additional 5 h at 25° C. The reaction was then quenched by the addition of 10 ml of water. The resulting solution was extracted with 2×10 ml of ethyl acetate and the organic layers combined. The resulting mixture was washed with 3×10 mL of brine. The resulting mixture was concentrated under vacuum. The residue was applied onto a TLC plate with PE/EA (1/1). This resulted in 50 mg (79%) of 1-[(4-[5-[3-chloro-5-(trifluoromethyl)phenyl]-5-(trifluoromethyl)-4,5-dihydro-1,2-oxazol-3-yl]-2-(trifluoromethyl)phenyl)carbonyl]imidazolidin-4-one as yellow oil.
