2-Chloro-3-Nitro-6-Trifluoromethyl Pyridine Use and Manufacturing

To a cooled (0 °C) mixture of fuming sulfuric acid (3.2 mL) and aqueous hydrogen peroxide (50percent, 1.6 mL) was added a solution of 3-amino-2-chloro-6-(trifluoromethyl)pyridine (304 mg, 1.55 mmol) in cone, sulfuric acid (4 mL). The reaction was slowly warmed to 25 °C and stirred 20 hours, whereupon the reaction mixture was poured into ice water. The mixture was neutralized with aqueous ammonium hydroxide, and then extracted with ethyl acetate (5 X 10 mL).The organic layers were dried over anhydrous sodium sulfate and concentrated to afford compound 5.1 (126 mg, 36percent) as a yellow solid that was used without further purification.C)
