Abstract
The synthesis and purification of zosteric acid is described. The specification describes methods for preparing p-coumaric acid, for preparing zosteric acid, and purifying zosteric acid. Zosteric acid is prepared from p-coumaric acid. Zosteric acid, however, need not be prepared by any particular method to be purified by a method of the invention. All three methods may be used in combination to prepare and purify zosteric acid.
