Reaction Steps

Compound 4 (2.0 g, 2.1 mmol, 1.0 eq.) was dissolved in anhydrous dioxane (30 mL), then anhydrous Cs2CO3 (684 mg, 2.1 mmol, 1.0 eq.) was added and then epibromohydrin (1.8 mL, 21.0 mmol, 10.0 eq.) was added dropwise. The reaction medium was then slowly heated to reflux. The mixture was stirred during 12 hours upon reflux then cooled to room temperature. EtOAc (10 mL) was then poured and the precipitate was filtered. EtOH (20 mL) was then added to the solution and the precipitate was filtered off. The remaining solution was analyzed by TLC. The first precipitate was washed thoroughly with EtOAc (30 mL). The organic solution was then evaporated and purified by column chromatography using silica gel (DCM/hexanes 80/20). The product was further recrystallized to give N-cyclohexyl-2-(4-(3,5-diiodo-4-(oxiran-2-ylmethoxy)phenoxy)-3,5-diiodophenyl)acetamide (93 mg, 0.1 mmol) as a powder. The second filtrate and the remaining solution were revealed by TLC to be the starting material which did not react.
