Abstract

PURPOSE: To prepare the titled compound useful as a synthetic intermediate of pesticides and pharmaceuticals, in high yield, by reacting glyoxylic acid with phenols in the presence of organic amines.
CONSTITUTION: Glyoxylic acid is made to react with a phenol of formula I (R1 and R2 are H, halogen, alkyl, alkoxy, etc.) in the presence of an organic amine (e.g. trimethylamine, piperidine, etc.) at or above room temperature, pref. at 65W90°C for 10W30hr. The pH of the produced liquid is adjusted to 1W3 by adding a mineral acid such as hydrochloric acid and sulfuric acid, and the unreacted phenol is extracted with a solvent such as benzene and removed to obtain the titled compound of formula II. The production of the objective compound is utterly impossible in the absence of the organic amines.
