2-Amino-3-nitro-6-picoline Use and Manufacturing
Synthesis of the 6-(1-ethyleneimine)-2-carbamoyl-3-nitropyridine (compound V) [Show Image] The reagents used was ( i ) HNO25.0 g (231 mmol) of 2-amino-6-picoline was cooled to -15(C, and dissolved very carefully in concentrated sulfuric acid (100 ml). This solution was cooled to 0(C, and 22.0 ml (60 percent, d = 1.42, 347 mmol) of nitric acid was added dropwise thereto. After the addition, the ice-water bath was removed, and after the heat generation was stopped, the reaction mixture was stirred at room temperature for 2 hours. Thereactionmixture was poured into ice (400 g), and the mixture was controlled to have pH of from 4 to 5 with aqueous 4 N sodium hydroxide solution added thereto. The precipitate formed was taken out through filtration, and washed with hot water. This was dried, and applied to a silica gel column chromatography. From the eluate with chloroform/methanol (50/1, v/v), 7.60 g (22 percent) of the entitled compound was obtained as a yellow solid.1H-NMR(DMSO-d6)δ: 2.37(3H, s), 6.61(1H, d, J=8.7Hz), 7.86(2H, brs), 8.24(1H, d, J=8.7Hz).
