Reaction Steps

The synthesis of a 2-halopyridine sulfonamide intermediate is illustrated in Reaction Scheme L. The 2-chloro-3-aminopyridine is converted to the 2-chloropyridinesulfonyl chloride by reaction with sodium nitrite/acid and sulfuryl chloride. This compound is then allowed to react with dibenzylamine to provide the desired 2-chloropyridine 3-sulfonamide intermediate. This compound may then be carried on to a final product using the methods described in Reaction Schemes A and D.
