Reaction Steps
6-Chloronicotinic acid 51 is activated by reacting with a chloroformate activating agent such as SOCl2, phenylchloroformate, or p-nitrophenyl chloroformate, or a carbodiimide activating agent such as CDI, DCC, or EDC in the presence of HOBt and N-hydroxysuccinimide in a polar aprotic solvent such as CH2Cl2, 1,2-dichloroethane, DMF, or NMP, and heating. An alcohol such as ethanol is then added to form 6-chloronicotinic acid ethyl ester 71.
