Procedure
Procedure G was used to couple 4-chloro-3-(pyridin-2-yl)aniline (50 mg) and 2-chloro-4-methylsulfonylbenzoic acid to produce 2-chloro-N-(4-chloro-3-(pyridin-2-yl)phenyl)-4-(methylsulfonyl)benzamide. MS (Q1) 421.0 (M)+. The product was then dissolved in 1 N HCl solution followed by freebasing with 0.5 N NaOH solution (pH to 11). The resulting precipitate was filtered and vacuum-dry.
