Reaction Steps

mCPBA (130 mg, 0.582 mmol) was added was added to a solution of ethyl trans-4-[1-(5-bromo-1,3-thiazol-2-yl)ethenyl]cyclohexanecarboxylate (182 mg, 0.529 mmol) in DCM (3 ml) at 0° C. The mixture was then allowed to stir at room temperature for 17 h, diluted with dichlormethane and washed with sodium hydroxide (2M in H2O). The aqueous layer was extracted with DCM and the combined organic layers were washed with brine, dried, concentrated in vacuo. The residue was purified on silica gel (0-15% EtOAc in hexane) to afford ethyl trans-4-[2-(5-bromo-1,3-thiazol-2-yl)oxiran-2-yl]cyclohexanecarboxylate. MS ESI calc'd. for C14H18BrNO3S [M+H]+ 360. found 360.
