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 1-(3-bromo-4-methyl-benzenesulfonyl)-azetidine (Intermediate 155), 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.
