m-Chloroperbenzoic acid → HCID 11436184, compound

Participants

Reaction Steps

A solution of mCPBA (70%, 4.46 g, 18.11 mmol) in DCM (100 ml) was added to a solution of methyl 5-bromonicotinate (3.11 g, 15.09 mmol) in DCM (100 ml). After stirring at room temperature for several hours, additional mCPBA (6.6 g, 26.77 mmol) was added (in portions) to drive the reaction to completion. After 4 days, the reaction mixture was sequentially washed with a saturated solution of sodium bicarbonate followed by water. The organic phase was dried over MgSO4, and concentrated to dryness. The crude material was purified by chromatography on silica gel using 50% EtOAc/hexanes to 100% EtOAc to give 1.16 g of the title product.
