Reaction Steps

A mixture of 5-methoxy-benzofuran-3 (2H)-one (1.64 g, 10 mmol) and (carboxymethylene)triphenylphosphorane (5.22 g, 15 mmol) was refluxed in toluene (100 ml) for 48 hrs. At the end, the reaction mixture was concentrated and loaded over silica-gel column. The column was eluted with hexane (500 ml) and later with 25% ethyl acetate. The product, ethyl(5-methoxy-1-benzofuran-3-yl)acetate, was obtained as a white oil. Yield: 1.6 g (68%); 235 (M+H).
