Reaction Steps

Under a nitrogen atmosphere, 60% oil sodium hydride (605 mg, 15.1 mmol) was added in portions to methanol (10 ml) under ice cooling. Twenty minutes later, a dimethylformamide (20 ml) solution of 2-bromo-3-hydroxypyridine (2.5 g, 14.4 mmol) was added to the resulting mixture. The reaction mixture was distilled under reduced pressure to remove methanol and to the residue was added methyl iodide (0.94 ml, 15.1 mmol). The mixture was stirred at room temperature for 3 hours.
