(4-羟基苯基) 丙-2-烯酸乙酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Compound 5 can be prepared, for example, by the following method. Namely, hydroquinone and acrylic acid chloride are reacted to obtain 4-hydroxyphenyl acrylate (Formula 6) as a half ester. On the other hand, a 4-alkoxycarbonyloxy benzoic acid is heated and refluxed in a mixture of carbon-tetrachloride (a solvent) and thionyl chloride, and excess thionyl chloride and carbon tetrachloride (solvent) are distilled off under reduced pressure to obtain a 4-alkoxycarbonyloxy benzoic acid chloride (Formula 7). Then, in the presence of a base such as trimethylamine, the 4-hydroxyphenyl acrylate (Formula 6) and the 4-alkoxycarbonyloxy benzoic acid chloride (Formula 7) are reacted to obtain the compound 5.
