実験手順

A solution of (1) (282 g; 1.34 mol), freshly distilled acrylic acid (230 ml; 3.35 mol), hydroquinone (1.9 g) and p-toluenesulfonic acid (23.7 g) in 1,1,1-trichloroethane (1.1 l) is refluxed for 10 hours. The reaction mixture is cooled to from 60° to 70° C. and stirred into 2.5 l of petroleum ether, and the precipitate is filtered off, washed with petroleum ether and dried at room temperature under reduced pressure for 24 hours.
