Reaction Conditions

Temperature80 °C

Reaction Steps

At 0° C., 304 mg (1.95 mmol, 1.3 eq.) of iodoethane and 415 mg (3.0 mmol, 2.0 eq.) of potassium carbonate were added to a solution of 405 mg (1.5 mmol) of 4-iodo-6-methoxypyridin-3-ol in 10 ml of acetone and the mixture was stirred at 80° C. overnight and concentrated under reduced pressure. The residue was triturated with water, filtered and dried under reduced pressure. Yield: 322 mg (purity 93%, 72% of theory)
