- Intermediate, its synthesis, and its use in a process for the preparation of 2,3-dihydro-2,2-dimethyl-7-hydroxybenzofuran
-
2,3-Dihydro-2,2-dimethyl-7-hydroxybenzofuran is prepared by reacting catechol with isobutylene oxide or with a compound having the general formula STR1 wherein R is halogen or hydroxyl, and X is halogen, in the presence of a base to form the intermediate 2-(2-hydroxy-2-methylpropoxy) phenol and then thermally dehydrating, rearranging and cyclizing the resulting intermediate phenol in the presence of an acid catalyst to form 2,3-dihydro-2,2-dimethyl-7-hydroxybenzofuran.
