Yield: 92%

Reaction Conditions:

with triethylamine at 90 - 100; for 0.166667 h;Reagent/catalyst;

Steps:

1.1 Preparation of 3,5-diacetoxybenzoic acid
A mixture of 7.7 g (0.05 mol) of 3,5-dihydroxybenzoic acid (1), 25 mL of acetic anhydride and 2 mL of triethylamine was mixed and stirred for 10 min and heated at 90 to 100 ° C. TLC was monitored. Product into the ice water, a large number of white precipitate generated, filtered to obtain a white solid is the crude product,Recrystallization from ethanol gave 11.0 g of white crystals (2) in 92% yield.
