Azobisisobutyronitrile → HCID 53960446, compound

Participants

Reaction Steps

A mixture of 71 g of methyl α-(5-methyl-3-benzo[b]thienyl)-β-methoxyacrylate (see Example 1 ), 57.8 g of N-bromosuccinimide, 1.1 g of azodiisobutyronitrile and 720 ml of carbon tetrachloride is refluxed for 75 minutes. The mixture is cooled to room temperature and filtered, and the filtrate is then concentrated under reduced pressure, and the yellow oil which remains is purified by chromatography on silica gel using diethyl ether/n-hexane (1:1). The crude product is crystallized from methylene chloride/n-hexane, and methyl α-(5-bromomethyl-3-benzo[b]thienyl)-β-methoxyacrylate is obtained in this manner as pale yellow crystals, m.p. 124°-125° C.
