Procedure

Following the general method as outlined in Intermediate 107, starting from (4-chloro-2-ethynyl-phenoxy)-acetic acid tert-butyl ester (Intermediate 3) and 4-bromo-N,N-diethyl-2-(isopropylsulfonyl)benzamide (Intermediate 257), the title compound was obtained as a brown sticky solid after purification by flash column chromatography (silica), eluting with cyclohexane containing increasing amounts of EtOAc.
