Abstract

PURPOSE: To prepare the title compound useful as an intermediate of penicillanic acid or its derivative, in high yield, by reacting phenol, glyoxylic acid, and ammonium carbonate in one batch, at low temperature.
CONSTITUTION: The objective compound is prepared by reacting glyoxylic acid or its precursor (1 mole) with phenol (≥1 mole, pref. 1W5 moles) and ammonium carbonate (≥1 mole, pref. 1W5 moles) in the presence of water or a mixture of water and an organic solvent, at 0W60°C. The compound can be separated from the reaction mixture at a purity of 90W99% by known process, and crystallized by conventional purification method. When the crystallization of the product takes place in the reaction system, the filtrate after the removal of the crystals can be used as the reaction solvent, which contributes to the effective utilization of the raw materials and the prevention of pollution of waste liquid.
EFFECT: The objective compound can be prepared without complicated operations and without using excessive ammonium salt.
