Reaction Steps

4-(5-(2-chlorophenylthio)-6-(3-(piperidin-4-yl)-1,2,4-thiadiazol-5-ylamino)pyridin-3-yloxy)benzaldehyde (154 mg, 0.294 mmol) was dissolved in methylene chloride (3 mL) and triethylamine (81.9 μL, 0.588 mmol) and acetic anhydride (33.3 μL, 0.353 mmol) were added. After stirring for 20 minutes, the reaction was poured into saturated aqueous sodium bicarbonate and extracted with methylene chloride. The organic layer was concentrated to afford 4-(6-(3-(1-acetylpiperidin-4-yl)-1,2,4-thiadiazol-5-ylamino)-5-(2-chlorophenylthio)pyridin-3-yloxy)benzaldehyde (161 mg, 0.284 mmol, 96.8% yield).
