実験手順
A mixture of 2,4-dihydroxypyridine (1.0 eq), K2CO3 (1.0 eq), and water was stirred at 100° C. so that it became homogeneous. With continued stirring and heating, I2 (1.0 eq) was added in portions, causing the evolution of gas. When the solid I2 was consumed, the mixture was cooled and acidified with aqueous KHSO4 (1.0 eq), generating a precipitate. The precipitate was collected by filtration, rinsed with water, and stored under high vacuum, to give 2,4-dihydroxy-3-iodopyridine.
