Reaction Steps

The reaction of catechol and methallyl chloride may be illustrated as follows: ##STR1## In accordance with existing processes the reaction mixture, I, would have been filtered to remove sodium chloride, then subjected to Claisen rearrangement and cyclization to form 2,3-dihydro-2,2-dimethyl-7-hydroxybenzofuran resulting in the loss of unreacted or excess catechol employed in the reaction.
