Methyl (2-Hydroxyphenyl)acetate
A solution of 15 gm (0.1 mole) of 2-hydroxyphenylacetic acid in 500 ml methanol and 2 ml concentrated sulfuric acid was placed in a Soxhlet extractor charged with 3 A molecular sieves.
The solution was heated to reflux for 72 hours, and the sieves were exchanged at 24-hour intervals.
The reaction medium was then evaporated to an oil which was dissolved in 100 ml toluene and extracted with 3*100 ml portions of water.
The toluene phase was dried over magnesium sulfate, treated with activated charcoal and evaporated to provide 13 gm (80percent yield) of a yellow oil.
The NMR spectrum was consistent with the assigned structure and this material was used in the next reaction step.
