Versuchsvorschrift

Procedure G was used to couple BOC-4-(aminomethyl)benzoic acid (48 mg) with 4-chloro-3-(pyridin-2-yl)aniline (35 mg). The crude reaction mixture was treated with TFA (1 mL) containing trace amounts of water for 1 h. The reaction mixture was concentrated to yield 4-(aminomethyl)-N-(4-chloro-3-(pyridin-2-yl)phenyl)benzamide. 4-(aminomethyl)-N-(4-chloro-3-(pyridin-2-yl)phenyl)benzamide (80 mg) was dissolved in DMF (5 mL) and treated with AcOH (10 L), paraformaldehyde (48 mg), and sodium triacetoxyborohydride (125 mg) for 16 h. The reaction mixture was concentrated, and the crude residue was dissolved in ethyl acetate and washed with 1 N sodium hydroxide, dried (MgSO4) and concentrated. The crude product was purified by reverse phase HPLC to yield N-(4-chloro-3-(pyridin-2-yl)phenyl)-4-((dimethylamino)methyl)benzamide. MS (Q1) 365.0 (M)+.
