実験手順
Following the general method as outlined in Intermediate 20, starting from (4-chloro-2-ethynyl-phenoxy)-acetic acid tert-butyl ester (Intermediate 3) and 1-ethyl-2-iodo-4-(methylsulfonyl)benzene (Intermediate 123), the title compound was obtained as an orange oil after purification by flash column chromatography (silica), eluting with cyclohexane containing increasing amounts of EtOAc.
