Abstract
The bromination of 6,7-dibenzyloxy-4-methylcoumarin has given 6,7-dibenzyloxy-3-bromo-4-methylcoumarin and this has been converted by the Perkin reaction into 5, 6-dibenzyloxy-3-methylbenzofuran and its 2-carboxy derivative. 5, 6-Dihydroxy-3-methylbenzofuran-2-carboxylic acid has been synthesized by the catalytic debenzylation of the latter compound.
