Reaction Steps
5-Chloro-3-nitro-2-aminopyridine is reacted with 2,2,3,3-tetrafluoropropionyl chloride to yield 5-chloro-3-nitro-2-(2,2,3,3-tetrafluoropropionamido)pyridine, which when hydrogenated yields 6-chloro-1-hydroxy-2-(1,1,2,2-tetrafluoroethyl)-1H-imidazo(4,5-b)pyridine. This compound is reacted with trimethylamine to prepare 6-chloro-1-hydroxy-2-(1,1,2,2-tetrafluoroethyl)-1H-imidazo(4,5-b)pyridine trimethylamine salt.
