反应详情

A mixture of 2-bromomethylacrylic acid (1.0 g, 6.0 mmol), 4-butoxybenzenesulfinic acid, sodium salt (3.1 g, 13 mmol), sodium carbonate (1.9 g, 18 mmol) and dimethylformamide ( 20 mL) is refluxed overnight. The reaction mixture is then partitioned between ethyl acetate and aqueous 10% hydrochloric acid and the organic phase is concentrated in vacuo. The concentrate is chromatographed over silica gel 60 (230-400 mesh) with chloroform/methyl alcohol/acetic acid (94/5/1) and the eluate concentrated in vacuo to afford the title compound as a white solid.
