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 3-bromo-N-(2,2-dimethyl-propyl)-4-methyl-benzenesulfonamide (Intermediate 145), the title compound was obtained after purification by flash column chromatography (silica), eluting with cyclohexane containing increasing amounts of EtOAc.
