Procedimiento
A solution of 1-[5-bromo-3-chloro-2-(oxiran-2-ylmethoxy)phenyl]ethanone (1.7 g, 5.6 mmol) and m-CPBA (2.4 g, 14 mmol) in DCM (30 ml) was heated to 50° C. After 22 h more m-CPBA (2.4 g, 14 mmol) was added and the mixture was heated at 50° C. for another 44 h and then brought to ambient temperature. The solid was filtered off and rinsed. The resulting filtrate was washed with sodium bicarbonate (saturated), brine and further dried (Na2SO4) and evaporated to dryness to give the crude title compound (2.7 g). MS m/z (rel. intensity, 70 eV) 280 (bp), 278 (84), 224 (54), 222 (52), 57 (79), 322 (M+, 5).
