Reaction Steps

To a solution of 2-(2,6-difluorophenyl)-5-(4-hydroxyphenyl)oxazole-4-carboxamide (0.100 g, 0.316 mmol) in DMF (5 ml) was added K2CO3 (0.066 g, 0.474 mmol). The resulting mixture was stirred at room temperature for 30 minutes, after which time epichlorohydrin (0.044 g, 0.474 mmol) was added. The reaction was heated to 100° C., stirred at this temperature for 2 h and then diluted with EtOAc before being washed with water and brine. Drying over Na2SO4 and removal of solvent under vacuum gave 2-(2,6-difluorophenyl)-5-(4-(oxiran-2-ylmethoxy)phenyl)oxazole-4-carboxamide (0.102 g, 0.274 mmol, 87%) as a golden oil. LCMS (1) 2.00 min; m/z (ES+) 374.
