PROBLEM TO BE SOLVED: To provide a vinylphenylpropionic acid derivative having an acid- decomposable substituent, and to provide a method for producing the same. SOLUTION: This derivative is, for example, a compound represented by the formula. The compound is produced, for example, by reacting t-butyl bromoacetate with tri-n-butylphosphine, reacting the produced corresponding quaternary phosphonium salt with a base, reacting the produced corresponding phosphorus ylide with 2,4,6-tris(3',5'-di-t-butyl-4'-hydroxybenzyl)methylstyrene, and then hydrolyzing the obtained corresponding quaternary phosphonium salt. |
