You should try 2eq of H2SO4 and reflux overnight, that should do the trick.

Subject: ORGLIST:An esterification that will not proceed!
Reaction of 4-hydroxy-3-methoxybenzoic acid (vanillic
acid, VA) with absolute ethanol in the presence of
catalytic amounts of sulfuric acid, will not produce
enough ethyl-4-hydroxy-3-methoxybenzoate! Does anyone
know why? What is the pKa of VA?
Save me that trip to the library! Thanks.
Badru
