5-Bromo-3-fluoro-2-pyridinecarbonitrile Use and Manufacturing

Step C: 5-Bromo-3-fluoro-pyridine-2-carbonitrile To a mixture of HStep C: 5-Bromo-3-fluoro-pyridine-2-carbonitrileTo a mixture of HTetrabutylammonium fluoride (26.3 ml, 26.3 mmol, 1M in THF) was charged to a round bottom flask and cooled to -40°C. This was treated with sulfuric acid (0.04 ml, 0.074 g, 0.750 mmol). It was then treated with DMF (18 ml) until the suspension became homogenous. To this mixture was added slowly a solution of 5-bromo-3- nitropicolinonitrile (2.0 g, 8.77 mmol) dissolved in DMF (32 ml). Once the addition was complete the reaction was allowed to stir at -40°C for 90 minutes and at roomtemperature for another 1 hour. The reaction was then quenched with 2 N HC1 (20 ml), then diluted with HStir amixture of S-bromo-S-fluoro-pyridine^-carboxylic acid amide (0.375 mg, 1.71 mmol) and NaCl (0.120 g, 2.05 mmol) in CH
