Procedure
(4-benzyloxy-phenyl)-acetic acid methyl ester (10 g; 0.04 mol)) was charged to toluene (100 ml). Further potassium carbonate (13.47 g; 0.09 mol), paraformaldehyde (2.9 g, 0.097 mol) and tetrabutyl ammonium iodide (0.72 g) were charged and the reaction mixture thus obtained was refluxed for 5.5-6 hours. The reaction mass was cooled to 25-30° C. and filtered. The filtrate contains 2-(4-benzyloxy-phenyl)-acrylic acid methyl ester.
