2-Hydroxy-4,5,6-trimethoxyacetophenone and 3,4-benzyloxybenzoyl chloride were prepared from readily available chemicals, 3,4,5- trimethoxybenzoic acid and 3,4-dihydroxybenzaldehyde, respectively. 5, 3',4'-TMhydroxyl-6,7-dimethoxyflavone was obtained by the reaction these two key intermediates under a PTC conditions.
