实验步骤: Into a 50-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed N,N-dimethylformamide (2 mL), 4-[5-(3,5-dichloro-4-fluorophenyl)-5-(trifluoromethyl)-4,5-dihydro-1,2-oxazol-3-yl]-2-methylbenzoic acid (50 mg, 0.11 mmol, 1.00 equiv), HATU (174 mg, 0.46 mmol, 4.00 equiv), DIEA (60 mg, 0.46 mmol, 4.00 equiv), 3-(3,3,3-trifluoropropyl)imidazolidin-4-one (25 g, 137.25 mmol, 1.00 equiv). The resulting solution was stirred for 2 h at room temperature. The crude product was purified by Prep-HPLC. This resulted in 22.1 mg (32%) of 1-([4-[5-(3,5-dichloro-4-fluorophenyl)-5-(trifluoromethyl)-4,5-dihydro-1,2-oxazol-3-yl]-2-methylphenyl]carbonyl)-3-(3,3,3-trifluoropropyl)imidazolidin-4-one as a white solid. 641 [Ms+CH3CN+H]+; (300 MHz, CD3OD, ppm): δ7.77-7.64 (m, 4H), 7.45-7.28 (m, 1H), 5.12-4.69 (m, 1H), 4.32-4.22 (m, 1H), 4.08-4.01 (m, 1H), 3.87-3.54 (m, 2H), 3.14-2.87 (m, 3H), 2.70-2.31 (m, 4H). Into a 50-mL round-bottom flask purged maintained with an inert atmosphere of nitrogen The crude product was purified by Prep-HPLC This resulted in 22.1 mg (32%) of 1-([4-[5-(3,5-dichloro-4-fluorophenyl)-5-(trifluoromethyl)-4,5-dihydro-1,2-oxazol-3-yl]-2-methylphenyl]carbonyl)-3-(3,3,3-trifluoropropyl)imidazolidin-4-one as a white solid

实验步骤: Into a 50-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed N,N-dimethylformamide (10 mL), 4-[5-[3-chloro-5-(trifluoromethyl)phenyl]-5-(trifluoromethyl)-4,5-dihydro-1,2-oxazol-3-yl]naphthalene-1-carboxylic acid (70 mg, 0.14 mmol, 1.00 equiv), HATU (74 mg, 0.19 mmol, 4.00 equiv), DIEA (218 mg, 1.69 mmol, 4.00 equiv), 3-(3,3,3-trifluoropropyl)imidazolidin-4-one (31 mg, 0.17 mmol, 1.00 equiv). The resulting solution was stirred for 2 h at room temperature. The crude product was purified by Prep-HPLC. This resulted in 32 mg (34%) of 1-[(4-[5-[3-chloro-5-(trifluoromethyl)phenyl]-5-(trifluoromethyl)-4,5-dihydro-1,2-oxazol-3-yl]naphthalen-1-yl)carbonyl]-3-(3,3,3-trifluoropropyl)imidazolidin-4-one as a light brown solid.
