2,3-Difluoropyridine-4-carboxylic acid is particularly important as starting materials for agrochemicals and pharmaceuticals. | [Synthesis]
To a solution of n-BuLi (26.1 mL, 52.09 mmol) in THF (70 mL, Na distilled) was added N,N-diisopropylamine (7.30 mL, 52.09 mmol) and 2,3-difluoropyridine (5.00 g, 43.41 mmol) successively at -78 °C. The resulting mixture was stirred at -78°C for 1 hour and |
