Procedure

A mixture of 52 g (0.29 moles) ethyl 3-bromopropionate and 36.1 g (0.29 moles) anhydrous sodium sulfite in 150 ml water was refluxed for about 16 hours. The reaction mixture was stripped. The residue was washed with acetone and ethyl ether, stripped, and dried in a vacuum oven to give 90.5 g of the above-identified product.
