HCID 346562-(4-Hydroxyphenyl)butanoic acid

Procedure

The m- or p-hydroxyphenyl alkanol can also be prepared using conventional techniques. For example, a m- or p-methoxyphenylbutyric acid can be reacted at reflux temperature with hydrogen bromide to form a m- or p-hydroxyphenylbutyric acid. This acid can then be reacted with borane in tetrahydrofuran to form m- or p-hydroxyphenylbutanol. This latter compound is reported in JACS, 84, 788 (1962).
