Reaction Steps

290 mg of dimethylamine hydrochloride was coupled to 1 g of 4-(tert-butoxycarbonyl)-3-chlorobenzoic acid via Procedure G. The reaction mixture was diluted with ethyl acetate, washed with 0.1 N HCl, 0.1 N NaOH and brine, dried (MgSO4) and evaporated to afford tert-butyl 2-chloro-4-(dimethylcarbamoyl)benzoate. 1.1 g of tert-butyl 2-chloro-4-(dimethylcarbamoyl)benzoate was treated with TFA (4 mL) containing trace amounts of H2O for 2 h. The reaction mixture was evaporated, and then added 0.1 N HCl. The resulting solid was filtered and washed with H2O to yield 2-chloro-4-(dimethylcarbamoyl)benzoic acid. 100 mg of 4-chloro-3-(pyridine-2-yl)aniline was coupled to 2-chloro-4-(dimethylcarbamoyl)benzoic acid via Procedure G. The product was purified on reverse phase HPLC to yield 2-chloro-N1-(4-chloro-3-(pyridin-2-yl)phenyl)-N4,N4-dimethylterephthalamide. MS (Q1) 414.1 (M)+.
