2-Amino-3-methyl-5-nitropyridine Use and Manufacturing
3-Methyl-pyridin-2-ylamine (5.0 g, 46.2 mmol) was dissolved in concentrated sulfuric acid (24ml), the mixture was chilled to 0°C and a mixture of fuming nitric acid (d=1.5, 3.5ml) and concentrated sulfuric acid (3.5ml) was added dropwise to the reaction mixture while temperature was kept below 20°C. 3-Methyl-pyridin-2-ylamine (5.0 g, 46.2 mmol) was dissolved in concentrated sulfuric acid (24ml), the mixture was chilled to 0C and a mixture of fuming nitric acid (d=1.5, 3.5ml) and concentrated sulfuric acid (3.5ml) was added dropwise to the reaction mixture while temperature was kept below 20C. The stirred mixture was allowed to warm to 20C and transferred in portions of 3-5ml into a second flask which was heated to 35-40C (the temperature was not allowed to rise over 40C - monitoring carefully the temperature after every addition of a new portion). The resulting reaction mixture was subsequently stirred for additional 30min at 50C, cooled to ambient temperature and neutralized with concentrated aqueous ammonia. This led to the formation of a precipitated which was filtered, washed with water and aqueous DMFA (50%, 6ml), and recrystallized from DMFA yielding
