実験手順

To a 250 mL round flask was added 2-chloro-3-iodo-4-aminopyridine (5.0 g, 19.6 mmol), thiophenol (2.16 g, 19.6 mmol), CuI (0.187 g, 0.98 mmol), ethylene glycol (2.5 g, 39 mmol), potassium carbonate (5.4 g, 39 mmol), and 150 mL of isopropanol. The reaction was heated to reflux and stirred under a nitrogen atmosphere for 24 h. After cooling, the mixture was purified by a silica gel column. Yield (91%) of 2-chloro-3-phenylthio-4-aminopyridine was 4.2 g.
