YieldReaction ConditionsOperation in experiment
at 100.0℃; for 15.0h;Sealed tube; Example 4((S -N-((R)-l-(5-benzyl-2-(2,5-difluorophenyl)oxazol-4-yl)-2,2-dimethylpropyl)-N- -4-fluoropyrrolidiii-3-yl)methyl)-2-hydroxypropanainide[00160] Ethyl 3-bromo-2-oxo-4-phenylbutanoate (3.0 g, 10.5 mmol) and 2,5- difluorobenzamide (4.0 g, 25.5 mmol) in a seal tube was heated at 100 C for 15 h. After cooled down, the precipitate was filtered off with methanol washes. After the filtrate was removed in vacuo, the crude product was purified by automated column chromatography (10% to 60% EtOAc in Hexanes). Ethyl 5-benzyl-2-(2,5-difluorophenyl)oxazole-4- carboxylate contaminated with inseparable side products was obtained (735 mg, 20.4%), which was used for the next step without any further purification. LC/MS (uplc): MH+ 344.1, 1.15 min.
