Reaction Steps

Stir a solution of 2-chloroisonicotinic acid (1.0 g, 6.3 mmol), 1-hydroxybenzotriazole (850 mg, 6.3 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (1.21 g, 6.3 mmol), dipropyl amine (862 μL, 6.3 mmol), and triethylamine (1.75 mL, 12.6 mmol) in dichloromethane (63 mL ) at room temperature over the weekend. Wash the solution with 0.1 N citric acid (2×50 mL), saturated aqueous sodium bicarbonate (50 mL), saturated aqueous sodium chloride (50 mL), dry (sodium sulfate), concentrate and purify (silica gel chromatography, eluting with 10:90 to 20:80 ethyl acetate:hexanes) to give the title compound (1.16 g, 76%).
