2'-HYDROXY-4',6'-DIMETHOXYACETOPHENONE synthesis

13synthesis methods
Preparation by reaction of acetonitrile on phloroglucinol dimethyl ether (Hoesch reaction).
-

Yield:90-24-4 100%

Reaction Conditions:

with potassium carbonate in acetone for 3 h;Reflux;

Steps:


To a refluxing solution of 2,4,6-trihydroacetophenone-monohydrate (10 g, 53.7 mmol) and K2CO3 (15 g, 108.7 mmol) in acetone (150 mL), (CH3)2SO4 was added at three hour intervals (3 x 3.5 mL, 40.0 mmol). The solution was filtered and the solvent was evaporated to afford 2,4-dimethoxy-6-hydroxyacetophenone as a yellow solid (98%).
