실험 절차

Following the general method as outlined in Intermediate 107, starting from (4-chloro-2-ethynyl-phenoxy)-acetic acid tert-butyl ester (Intermediate 3) and 2-bromo-1-chloro-4-(propylsulfonyl)benzene (Intermediate 126), the title compound was obtained as a colorless oil after purification by flash column chromatography (silica), eluting with cyclohexane containing increasing amounts of EtOAc.
