    摘要: The invention provides a process for the preparation of 4-(p-methoxyphenyl)-2-aminobutane represented by structural formula (1) as shown herein below: [C11H17ON=4-(p-methoxy phenyl)-2-amino butane] said process comprising the steps of, (a) isolating a phenolic compound 4-hydroxyphenyl)-butan-2-ol from the leaves of Taxus wallichiana by known methods, (b) treating the phenolic compound in aqueous mineral acid to obtain a phenolic halide derivative, (c) converting the phenolic halide derivative into its methyl ether by treating it with a methating agent, (d) reacting the methyl ether halide with azide to obtain an azido derivative, and (e) hydrogenating the azido compound to obtain 4-(p-methoxyphenyl)-2-aminobutane.
