3-Hydroxybenzoic Acid → HCID 20450556, compound

Participants

Reaction Steps

Substantially equimolar amounts of 2,6-dichloroquinoline and the potassium salt of 3-hydroxybenzoic acid are reacted, in an inert organic solvent, e.g., dimethylsulfoxide giving 5-(6-chloro-2-quinolinoxy)benzoic acid which is nitrated, with, for example, potassium nitrate in the presence of concentrated sulfuric acid to give the corresponding 2-nitrobenzoic acid. The 2-nitrobenzoic acid is then reacted with a suitably substituted--halo compound, e.g., 2-chloropropionate, as described hereinabove.
