Lithium borohydride → (5-Benzyl-2-(2,5-difluorophenyl)oxazol-4-yl)methanol

Participants

Reaction Steps

To a solution of ethyl 5-benzyl-2-(2,5-difluorophenyl)oxazole-4-carboxylate (590 mg, 1.72 mmol) in THF (8.6 mL) was slowly added LiBH4 (56.2 mg, 2.58 mmol) at room temperature. The reaction mixture was stirred for overnight. After quenched with water, the reaction mixture was extracted with EtOAc. The organic layers was washed with saturated NaHCO3 solution and brine, dried over anhydrous Na2SO4, filtered, and concentrated. The crude product was purified by automatic column chromatography (0 to 100% EtOAc in Hexanes) to yield (5-benzyl-2-(2,5-difluorophenyl)oxazol-4-yl)methanol (460 mg, 88%) as a white solid. LC/MS (uplc): MH+ 302.2, 0.92 min.
