Methyl 2-chloroacrylate → HCID 59437102, compound

Participants

Reaction Steps

To a suspension of 29 g of the compound obtained in Step B (103 mmoles) in 800 mL of dichloroethane there are added in succession 24 g of tosyl chloride (124 mmol), 12.6 mL of methyl 2-chloroacrylate (124 mmol) and then 35 mL of triethylamine (247 mmoles). The whole is stirred at reflux for 2 hours. After cooling, the reaction mixture is diluted with ethyl acetate, and the organic phase is washed with a saturated NaCl solution until neutral. After drying over MgSO4, filtration and concentration to dryness, the title product is isolated by chromatography over silica gel (petroleum ether/AcOEt gradient: 0-20%) in the form of a solid.
