Versuchsvorschrift

A mixture of 2-(6-chloro-5-methylpyridin-3-yl)acetic acid 74-4 (57 mg, 0.31 mmol), 2,3′-bipyridin-6′-amine 124-1 (51 mg, 0.30 mmol), 1,3-dicyclohexylcarbodiimide (75 mg, 0.36 mmol) and 4-(dimethylamino)pyridine (6 mg, 0.06 mmol) in DMF (1.2 mL) was stirred at room temperature for 10 hours. The reaction mixture was filtered through celite, washed and diluted with ethyl acetate (30 ml) and extracted with water 930 ml×2). The organic phase was dried over Na2SO4 and concentrated by evaporation. The residue was subjected to silica gel column chromatography with ethyl acetate as eluent to give N-(2,3′-bipyridin-6′-yl)-2-(6-chloro-5-methylpyridin-3-yl)acetamide 124-2 as white solid.
