| Abstract: | 2-Substituted-amino-3-fluoropyridine compounds(2a~2g) were synthesized by substitution and reduction from 2,3-difluoro-5-chloropyridine.A series of pyridine boric acid compounds(3a~3g) were obtained by reaction of 2 with n-butyllithium and triisopropyl borate.Finally, seven novel potassi-um(3-fluoro-2-amino substituted pyridin-4-yltrifluoroborates) were synthesized by substitution of 3a~3g with potassium hydrogen fluoride, respectively.The structures were characterized by 1 H NMR, 13 C NMR, IR, ESI-MS and elemental analysis. |
