171178-45-3 - Reference Information
| Introduction | 5-(N-tert-butoxycarbonylamino) 2-chloropyridine and its derivatives are a very useful class of aminopyridine derivatives as important pharmaceutical intermediates. |
| preparation | add 200 mL of 5-amino-2-chloropyridine and buffer solution consisting of sodium carbonate and sodium bicarbonate to a three-necked flask with stirring device, in an ice bath, tert-butyl dicarbonate was added dropwise to the dropping funnel. The reaction was stirred in a water bath at 30 °c for 22 hours. The reactant was extracted with diethyl ether (100 ml× 2) to remove unreacted tert-butyl dicarbonate, and the resulting aqueous phase was adjusted to Ph 2-3 with 3mol/L aqueous hydrochloric acid, then it was extracted with ethyl acetate (100 ml× 4), dried over anhydrous sodium sulfate, filtered, and the solvent was removed by rotary evaporator, 5-(N-tert-butoxycarbonylamino)-2-chloropyridine is obtained as a colorless oil liquid. |
