2-Methyl-5-hydroxypyridine → 2-Bromo-6-methylpyridin-3-ol

Participants

Reaction Steps

With cooling with ice, N-bromosuccinimide (18 g) was added to a pyridine (75 ml) solution of 6-methylpyridin-3-ol (10 g), and stirred at room temperature for 4 hours. After further stirred overnight at 50° C., the solvent was evaporated away under reduced pressure. The residue was dissolved in ethyl acetate, and washed with aqueous saturated sodium hydrogencarbonate solution and saturated saline water. After dried, the solvent was evaporated away, and the residue was crystallized with chloroform to obtain the entitled compound as a white solid.
