반응 단계
5-bromo-2-(oxiran-2-ylmethoxy)phenyl formate (12.6 g, 46.0 mmol) was dissolved in dioxane (50 ml) and KOH (10%)/NaOH (20%) was added. Water and EtOAc was added and the phases were separated. The combined organic phases were washed with brine and dried to give the title compound (10.3 g). MS m/z (rel. intensity, 70 eV) 245 (M+, 96) 244 (M+, bp), 213 (29), 189 (46), 188 (49).
