Reaction Steps
Esterification of 2,6-dichloronicotinic acid (25.5 g, 0.1328 mmol) in EtOH (200 proof, 200 mL) catalyzed with 96% H2SO4 (1.7 g) at refluxing temperature for 40 h under N2 gave the desired ethyl 2,6-dichloronicotinate as grey solid (24.89 g, 0.1131 mmol, yield 85.2%) after a normal work-up.
