Procedure
4.2 g of methyl 2-chloro-4-(methylsulfonamido)benzoate was hydrolyzed via Procedure M. 1 g of 4-chloro-3-(pyridin-2-yl)aniline was coupled to 1.35 g of 2-chloro-4-(methylsulfonamido)benzoic acid via Procedure G. The crude product was purified by reverse phase HPLC to yield 2-chloro-N-(4-chloro-3-(pyridin-2-yl)phenyl)-4-(methylsulfonamido)benzamide. MS (Q1) 436.1 (M)+.
