Three alkanolamines, 3, 4-dihydroxy-, 3, 4-dimethoxy-, and 3, 4-methylenedioxy-N-methylephedrines, were prepared from piperonylpropiophenone. This latter easily underwent demethylenedioxidation by treatment in nitrobenzene with anhydrous aluminum chloride at 20-30° to give 3, 4-dihydroxypropiophenone in a good yield.
