3-Pyridineacetic acid → HCID 10709719, compound

Participants

Reaction Steps

1-Boc-piperazine (12 g, 64 mmol), 3-pyridylacetic acid (8.85 g, 64 mmol), and HOBt (8.64 g, 64 mmol) were dissolved in DMF. To this solution, EDCI (14.7 g, 76.8 mmol) was added in portions. The mixture became homogenous and was stirred for 3 h. The mixture was diluted with water and ethyl acetate. The layers were separated, and the aqueous layer extracted with ethyl acetate. The organic layers were washed with water and brine, dried (Na2SO4), filtered, and concentrated to provide a yellow solid. The crude product was purified by recrystallization from hexanes:dichloromethane to provide 1-Boc-4-[(3-pyridinyl)acetyl]piperazine (13.5 g, 69%) as a white solid.
