Versuchsvorschrift
Following the general method as outlined in Intermediate 20, starting from (2-ethynyl-6-methyl-pyridin-3-yloxy)-acetic acid tert-butyl ester (Intermediate 86) and 1-bromo-3-(propane-1-sulfonyl)-benzene (Intermediate 5), the title compound was obtained as a yellow sticky solid after purification by flash column chromatography (silica), eluting with cyclohexane containing increasing amounts of EtOAc.
