Procedure

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-methoxy-ethyl)-4-methyl-benzenesulfonamide (Intermediate 149), the title compound was obtained as a orange sticky solid after purification by flash column chromatography (silica), eluting with cyclohexane containing increasing amounts of EtOAc.
