ABSTRACT:
4-Hydroxy-3-methoxyphenylacetone, an intermediate for methyldopa, has been prepared from reacting two moles of guaiacol and one mole of a 2-alkoxy propanol followed by basic elimination to form the enol ether of 4-hydroxy-3-methoxy phenyl acetone. The enol ether is subsequently converted to 4-hydroxy-3-methoxy phenyl acetone upon treatment with a strong acid.
