Reaction Steps

1-Hydroxy-7-methoxy-1,3-dihgydrobenzo[c]furan (1.08 g), which was prepared with using 7-methoxyphthalide which was synthesized with using 3-methoxybenzaldehyde by the method described in Journal of Organic Chemistry, 1980, 45, 1835-1838, was dissolved in chloroform (20 ml). Methyl (triphenylphosphoranylidene)acetate (2.68 g) was added to the solution. The mixture was stirred for 40 min. at 50° C. A temperature of the reaction mixture was down to room temperature. The reaction solution was purified by column chromatography on silica gel (n-hexane:ethyl acetate=2:1) to give the title compound (1.25 g) having the following physical data.
