Efficient and selective synthesis of alkoxy substituted di(pyridin-2-yl)amines and N-arylpyridin-2-ylamines
The formation of alkoxy substituted di(pyridin-2-yl)amines and N-arylpyridin-2-ylamines by nitro group reduction is described. Unexpected substitution of ortho with the amino at C-6 was observed during the reduction using SnCl2·2H2O
