Versuchsvorschrift

Into a 25-mL round-bottom flask, was placed a solution of 4-[5-[3-chloro-5-(trifluoromethyl)phenyl]-5-(trifluoromethyl)-4,5-dihydro-1,2-oxazol-3-yl]-2-(trifluoromethyl)benzoic acid (100 mg, 0.20 mmol, 1.00 equiv) in N,N-dimethylformamide (2 mL), imidazolidin-4-one (34 mg, 0.39 mmol, 2.00 equiv), HATU (150 mg, 0.39 mmol, 2.00 equiv), DIEA (51 mg, 0.39 mmol, 2.00 equiv). The resulting solution was stirred for 1 h at rt. 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 silica gel column with ethyl acetate/petroleum ether (1:0). This resulted in 100 mg (88%) 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.
