Participants

Reaction Steps

Sodium bicarbonate (0.42 g, 5.0 mmol) is added to the above bromide (1.33 g, 4.55 mmol) in 13 ml of dry DMSO. The mixture is heated at 90° for 1.75 hours, then cooled, worked up and dried. The solvent is removed and the crude product is purified by prep. TLC to give ethyl 2-acetyl-6-chloronicotinate. Following the procedure of Example 11, the ethyl 2-acetyl-6-chloronicotinate is reacted with lithium hydroxide monohydrate to give 2-acetyl-6-chloronicotinic acid.
