To a vigorously stirred mixture of hydroxycarbonimidic dibromide (15.5 g, 76.4 mmol) and ethyl acrylate (15.3 g, 153 mmol) in DMF (200 mL) was added a solution of 15 wt % aqueous KHCO3 (102 mL, 153 mmol). The mixture was stirred at room temperature overnight. Water was added and the mixture was extracted twice with methyl tert-butyl ether. The combined extracts were washed with brine, dried (Na2SO4) and concentrated in vacuo to give the title compound.
