Versuchsvorschrift
Following the general method as outlined in Intermediate 79, starting from (4-cyano-2-ethynyl-phenoxy)-acetic acid tert-butyl ester (Intermediate 46) and 2-iodo-1-methyl-4-(phenylsulfonyl)benzene (Intermediate 114), the title compound was obtained as a brown sticky solid in 89% yield.
