Participants

Reaction Steps

The title compound was prepared from anisole (11 g, 102 mmol) and succinic anhydride (i2 g, 120 m mol) in presence of anhydrous aluminum chloride (30 g) by the same method as described for 2 above to furnish 4-(4-methoxyphenyl)-4-oxo-butanoic acid in 84.6% yield, which on purification and crystallization from methanol/ethyl acetate (1:9) produced white crystals of 3, mp142–43° C., analyzed for C11,H12, O4 (found C64.21, H5.86; requires C63.45, H5.80%).
