Reaction Steps
To a solution of 6-Chloro-nicotinic acid (3.00 g, 19.0 mmol) in 30 mL dimethylformamide was added (benzotriazol-1-yloxy)tripyrrolidinophosphonium hexafluorophosphate (10.9 g, 20.9 mmol), 1-methylpiperazine (2.30 g, 22.1 mmol) and triethylamine (2.18 g, 21.5 mmol). After stirring for 18 hours, this was partitioned between ethyl acetate and water. The ethylacetate layer was dried over anhydrous sodium sulfate, concentrated in vacuo, and purified by flash chromatography (elution with 3% methanol/dichloromethane) to yield (6-Chloro-pyridin-3-yl)-(4-methyl-piperazin-1-yl)-methanone (2.50 g, 9.33 mmol).
