An efficient one-pot method for the synthesis of tert-butyl 6-aminonicotinate (5) is described. The key transformation involves displacement of the chloro group in tert-butyl 6-chloronicotinate (2) with azide followed by a Staudinger reaction. The scope of this methodology is further extended for the synthesis of a series of carboxylate-substituted heteroaryl amines. In particular, we synthesized tert-butyl carboxylate-substituted amino-pyridine, -pyridazine, and -pyrazine. In addition to one-pot conversion, short reaction time, simplicity of operation, ease of purification, and good yields are the key advantages of this methodology.

The 3-oxide of 2-p-nitrophenylimidazopyridine (8) may be obtained in good yield by base-induced cyclisation of 2-nitro-3-(p-nitrobenzylamino)pyridine (18).It is also obtained in lower yield, along with p-nitrobenzoic acid and other cleavage products, by the corresponding reactions of bases with the N-ethoxycarbonyl, N-methylsulphonyl, and N-p-tolylsulphonyl derivatives of 2-nitro-3-(p-nitrobenzylamino)pyridine .Cleavage is the main reaction when N-(2-nitro-3-pyridyl)-N-phenacylmethanesulphonamide (17) is treated with bases: phenylglyoxal, or its Schiff base with 3-amino-2-nitropyridine, are possible intermediates in the cleavage process. 3-Nitro-2-(p-nitrobenzylamino)pyridine (31) is similarly cyclised in basic media to give the 1-oxide of 2-p-nitrophenylimidazopyridine (32).
