Reaction Steps
5-bromo-3-fluoro-2-(oxiran-2-ylmethoxy)phenyl acetate (2.6 g, 8.7 mmol) was stirred in dioxane at RT. Aqueous KOH (10%) was added until basic pH was reached (1:1 water/KOH (10%)). Water was added and the solution was extracted with EtOAc: The combined organic phases were washed with brine, dried and evaporated to dryness to give the title compound (0.8 g). MS m/z (rel. intensity, 70 eV) 263 (M+, 97), 262 (M+, bp), 218 (39), 207 (50), 206 (51).
