Procedure
5-Chloro-6-[(2,4-dimethoxybenzyl)amino]nicotinate was treated with sodium hydroxide in ethanol to obtain 5-chloro-6-[(2,4-dimethoxybenzyl)amino]nicotinic acid. To the compound were added toluene, diphenylphosphoryl azide (DPPA), tert-butyl alcohol, and triethylamine, and the whole was stirred under reflux with heating. The resulting compound was treated with trifluoroacetic acid to obtain 3-chloropyridin-2,5-diamine.
