titleOfInvention |
Process for producing 2-halo-nicotinic acid derivatives and precursors thereto |
abstract |
A process for preparing a compound of the formula (I)n nwhich comprises a base-catalyzed reaction of a compound of thenformula (V).n nwith a compound of the formula (VI)n nwherein X is C1 or Br and Y is a carbonyl group, to thereby formnsaid compound of the formula (I). In addition a process fornproducing a 2-pyridinecarboxylate compound, comprisingncarbonylating a specific 2-fluoronicotinic acid compound in thenpresence of CO, an alcohol, and a transition metal catalyst. |
