Reaction Steps

6-Chloro-pyridine-2-carboxylic acid (1.00 g, 6.35 mmol) was dissolved in DCM (20 mL) and HOBt (1.03 g, 7.62 mmol), EDC.HCl (1.46 g, 7.62 mmol) and 1-(3-aminopropyl)imidazole (0.95 g, 7.62 mmol) were added. The reaction mixture was stirred for 18 h, diluted with DCM (130 mL) washed with sat aq Na2CO3 (100 mL), brine (30 mL), water (30 mL), dried (MgSO4) and concentrated in vacuo. The residue was triturated with water to give the crude title compound (1.05 g, 63%) as an off-white solid. LCMS (ES+): 266 [MH]+.
