Abstract
The invention provides a method for producing 4-(2'-methoxyethyl)phenol by brominating 4-hydroxyacetophenone to produce alpha-bromo-5-hydroxyacetophenone, and then causing a methoxide-bromide exchange to thereby produce alpha-methoxy-4-hydroxyacetophenone; and then conducting a single step reduction of alpha-methoxy-4-hydroxyacetophenone with at least two equivalents of hydrogen per equivalent of alpha-methoxy-4-hydroxyacetophenone in the presence of a hydrogenation catalyst to thereby directly produce 4-(2'-methoxyethyl)phenol.
