Procedure
A solution of N-(3-Bromo-2-cyanophenyl)-benzenesulfonamide (Intermediate 21, 0.22 g) and tributyltin azide (0.43 g) in 1,2-dichlorobenzene (1.5 mL) was heated by microwave irradiation at 130° C. for 2 hours. The mixture was diluted with ether and extracted with aqueous 1M sodium hydroxide. The aqueous solution was acidified with 1N hydrochloric acid to pH 1 and then extracted with ethyl acetate. The organic solution was washed with brine and then dried with sodium sulfate, filtered and the filtrate was evaporated. The residue was triturated with ether and the solid was collected by filtration to give the title compound as a colorless solid (0.19 g).
