HCID 90266Methyl 4-methoxyphenylacetate

Procedure

A solution of 25.3 g (152 ml) of (4-methoxyphenyl)acetic acid in dry methanol (250 ml) was mixed with 2 ml of conc. sulfuric acid and heated under reflux for 16 h. The cooled reaction solution was concentrated in vacuo, added to ice-water and extracted four times with 70 ml of ethyl acetate each time. The combined organic extracts were washed with saturated NaCl solution and dried over magnesium sulfate, and the solvent was removed in vacuo.
