Different methods were used for synthesizing hydratropic alcohol.Hydratropic alcohol was obtained by catalytic hydragenation of epoxide which was prepared from α-methylstyrene by oxidation with peracetic acid of low concentration.Total yield of this method was 39.5%. Hydratropic aldehyde was prepared by isomerization of epoxide in 58.6% yield,and hydratropic alcohol was obtained by reducing hydratropic aldehyde with sodium borohydride.Total yield of this method was 47.6%. Hydratropic alcohol was also obtained by catalytic hydrogenation of β-methylenephenethyl alcohol,which was given from chlorination,esterification and saponification of α-methylstyrene. Total yield of this method was 39.0%.Merits and defects of different synthetic routes were compared.
