An efficient and straightforward synthesis of a novel m-phenylene derivative has been developed. The optically pure dibromo compound was selected as a starting material. Through a protocol involving the Prins reaction and two steps of the Horner-Wadsworth-Emmons reaction, the basic skeleton was constructed with appropriate alpha and omega side chains. The compound proved to be a highly selective EP(4) agonist and a possible drug candidate for maturation of the uterine cervix.
