Abstract

Procedure for the preparation of derivatives of alpha-phenylpropionic acid, which correspond to the formula **(See formula)** wherein A is -COOH, -CN, -COOR1 and R1 is an alkoyl of 1 to 3 carbon atoms, characterized in that a compound of the formula is methylated **(See formula)** in which Y is -CN, -COOR1 and R1 is an alkoyl of 1 to 3 carbon atoms, with the help of a methylating agent in the presence of aqueous NaOH and a catalyst chosen from the group consisting of tetraalkylphosphonium salts, tetra-alkoxylammonium, tetra-alkoylarsonium, tetra-arylphosphonium and tetra-arylarsonium, as well as mixed alkoyl-aryl salts of phosphonium and arsonium, eventually obtaining the product obtained.
