The two synthetic methods of -(4-hydroxyphenylethyl) alcohol is discussed in this paper. The different of them is proposed also. The product and its intermediates were confirmed by IR/H NMR and the purity of them was analysed by Melting Point and HPLC. The effects of various conditions to reaction were studied. The reaction mechanisms were discussed.In phenylethyl alcohol method -(4-hydroxyphenylethyl) alcohol was synthesized by esterification,nitrofication,reduction and diazo-tization from -phenylethyl alcohol in 24.0% overall yield. The number of o/p is 0.267 by selective nitrofication because of molecular sieve.In ester reduction method the 51.2% yield of product was obtained from 4-hydroxyphenylacetic acid via two steps. The optimum conditions were attained by the orthogonal experiment.
