実験手順

Into a 25-mL round-bottom flask, was placed 1-amino-3-(2,2,2-trifluoroethyl)imidazolidin-2-one (90 mg, 0.49 mmol, 1.00 equiv), 4-[5-(3,5-dichlorophenyl)-5-(trifluoromethyl)-4,5-dihydro-1,2-oxazol-3-yl]-2-methylbenzoic acid (200 mg, 0.48 mmol, 0.97 equiv), EDCI (192 mg, 1.00 mmol, 2.04 equiv), HOBT (135 mg, 1.00 mmol, 2.03 equiv), triethylamine (303 mg, 2.99 mmol, 6.09 equiv), dichloromethane (10 mL). The resulting solution was stirred for 30 h at room temperature. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:1). This resulted in 39 mg (13%) of 4-[5-(3,5-dichlorophenyl)-5-(trifluoromethyl)-4,5-dihydro-1,2-oxazol-3-yl]-2-methyl-N-[2-oxo-3-(2,2,2-trifluoroethyl)imidazolidin-1-yl]benzamide as a white solid. (ES, m/z): 583 [M−H]−; 1H NMR (300 MHz, CDCl3) δ 7.89 (s, 1H), 7.43-7.62 (m, 6H), 4.06-4.12 (m, 1H), 3.54-3.89 (m, 7H), 2.47 (s, 3H).
