- W2364455399 abstract "p-Hydroxyphenylethyl alcohol is an important medicine intermediate.At present,the synthetic methods of p-hydroxyphenylethyl alcohol are not suitable for large-scale industrial application due to the long synthetic route,low overall yield,rigorous reaction conditions and high cost.In this paper,various of modified potassium borohydride systems were studied in the reduction of p-hydroxyphenylacetate methyl.KBH4-ZnCl2 displayed high reduction activity,and the optimum conditions were determined:n(KBH4):n(p-hydroxyphenylacetate methyl)=1.5:1,n(ZnCl2):n(KBH4)=1:1.5,reaction temperature 66℃(reflux),reaction time 6 h.The yield was 82.7% and the purity was 98.6% under the optimum conditions." @default.
