The preparation of a series of 2-pyridinamines and their alkyl derivatives is described.The target compounds are synthesized starting from corresponding 2-cyanopyridines

via incomplete hydrolysis in the presence of hydrogen peroxide in the dilute alkaline mixture of acetone-2% sodium hydroxide solution

and Hoffmann degradation reaction with freshly made NaBrO.This route is of industrial value because of cheap and readily available materials

moderate reaction conditions and convenient operations.
