Dimethylformamide → 2-Propenoic acid, 2-methyl-, 2-[4-(chlorocarbonyl)phenoxy]ethyl ester

Participants

Reaction Steps

62.56 g of 4-methacryloyloxyethyloxybenzoic acid was charged to a flask with 0.5 g dimethyl formamide , and 54.38 ml of thionyl chloride was added dropwise under stirring. The reaction was exothermic. The reaction mixture was stirred overnight to give a clear brownish solution. The excess thionyl chloride was drawn off under vacuum. The residue was digested once with 20 ml of distilled toluene, and the toluene drawn off under vacuum. The residue was directly usable.
