A Convenient Synthesis of Nicotinate Esters from 3-Cyanopyridones
Paine, John B.
, p. 351 - 355 (2007/10/02)
A convenient synthesis of alkyl-substituted ethyl nicotinates 8 was devised, using 3-cyano-2(1H)-pyridones 4.These were converted to the corresponding 2-bromo-3-cyanopyridines 5 with boiling phosphorus tribromide.The resulting 5 were smoothly debrominated
