실험 절차
Following the general method as outlined in Intermediate 20, starting from (4-chloro-2-ethynyl-phenoxy)-acetic acid tert-butyl ester (Intermediate 3) and 2-iodo-4-(methylsulfonyl)-1-propylbenzene (Intermediate 62), the title compound was obtained as a white solid after purification by flash column chromatography (silica), eluting with cyclohexane containing increasing amounts of EtOAc
