Participants

Reaction Steps

To a solution of 2-(2,6-difluorophenyl)-5-(3-formylphenyl)oxazole-4-carboxamide (0.050 g, 0.152 mmol), morpholine (0.027 mL, 0.305 mmol) and sodium triacetoxyborohydride (0.014 g, 0.228 mmol) in 1,2-dichloroethane (6 mL) was added acetic acid (0.013 mL, 0.228 mmol) at room temperature. The resulting mixture was stirred at room temperature for 2 h and then quenched with saturated sodium bicarbonate. The aqueous layer was extracted with ethyl acetate and the combined organic extracts dried over MgSO4 and concentrated in vacuo to give a residue that was purified by preparative HPLC to afford 2-(2,6-difluorophenyl)-5-(3-(morpholinomethyl)phenyl)oxazole-4-carboxamide (0.022 g, 0.056 mmol, 37%) as a white solid. 1H NMR (DMSO) δ 2.39 (4H, br m), 3.54 (2H, br m), 3.59 (4H, t), 7.38-7.45 (3H, m), 7.50 (1H, t), 7.71-7.78 (3H, m), 8.13-8.17 (2H, m). LCMS (2) Rt: 2.62 min; m/z (ES+) 400.
