Participants

Reaction Steps

To the solution of 2-choronicotinic acid (5 g, 31.84 mmol) in dry DCM under nitrogen, Oxalyl chloride (38.21 mmol) and catalytic amount of N,N-dimethylformamide were added carefully with stirring. The reaction was stirred for 3 hr. The solution was concentrated under vacuum to yield 2-chloronicotinyl chloride as solid which was used for next reaction without purification.
