Hydrochloric Acid → Picolinimidamide

참여 물질

반응 단계

To the solution of LiHMDS (5.18 g, 0.026 mmol, 1.3 equiv.) was added picolinonitrile (2.08 g, 0.02 mmol, 1 equiv.) at ice-bath and kept stirred for 2 h. Then, the reaction mixture was acidified with aqueous HCl (4N) to pH2, cooled at ice-bath and kept stirred. Then, the mixture was extracted with EA (200 mL×5). The combined organic phase was washed with brine, dried (Na2SO4), and evaporated to get picolinimidamide (2.0 g, 83%). LC-MS (m/z)=122 [M+H]+.
