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 6-iodo-2,3-dihydro-1-benzothiophene 1,1-dioxide (Intermediate 234), the title compound was obtained as a beige solid after purification by flash column chromatography (silica), eluting with cyclohexane containing increasing amounts of EtOAc.
