It was found that application of thionyl chloride to p-hydroxy- or p-benzyloxy-benaoic acid sometimes resulted in formation of a polyester, same as in the case of previously reported vanillide and tetravanillide. In addition, it was found that the formation of polyester depended on the properties of thionyl chloride used, the polyester being formed when thionyl chloride used was left in a clear glass ampule under irradiation of sunlight over a long period of time or irradiated with ultraviolet ray. It follows, therefore, that preparation of acid chloride should be carried out in the presence of pyridine or by the use of thionyl chloride preserved under protection from direct sunlight.
