FREMGANGSMAADE TIL FREMSTILLING AF 2-(4-HYDROXYPHENYL)-3-METHYLSMOERSYRE |
摘要 |
An integrated process for the preparation of 2-(4-hydroxyphenyl)-3-methylbutyric acid from the corresponding 2-(4-chlorophenyl)-3-methylbutyronitrile through hydrolysis of the nitrile by strong base to the corresponding carboxylic acid followed by formation of the corresponding phenol by nucleophilic displacement of the chlorine with a strong base in the presence of copper salts, and if so desired metallic copper, is described. |
