YieldReaction ConditionsOperation in experiment
96 g With N-Bromosuccinimide In chloroform at 20 - 80℃; for 1.5 h; Cooling with ice Production Example 59-1
71 g of N-bromosuccinimide was added to a mixture of 65 g of 5-trifluoromethyl-pyridine-2-ylamine and 100 mL of chloroform by being divided into 5 portions under ice water-cooling, The temperature was elevated to room temperature and the mixture was stirred for 1 hour.
Then, the mixture was heated to 80°C and was heated and stirred for 3C minutes.
After allowing the mixture to cool to room temperature, a saturated aqueous sodium thiosulfate solution and a saturated aqueous sodium hydrogen carbonate solution were added to the mixture, which was then subjected to extraction using chloroform.
A combined organic layer was dried using sodium sulfate, and then, was condensed under reduced pressure.
The residue was subjected to silicagel column chromatography to obtain 96 g of 3-bromo-5-trifluoromethyl-pyridin-2-ylamine. 3-bromo-5-trifluoromethyl-pyridin-2-ylamine 1H-NMR (CDCl3) δ: 8.27 (1H, d), 7.86 (1H, d), 5.38 (2H, brs).
