Acetyl chloride → HCID 117643681, compound

Participants

Reaction Steps

Sodium hydrogen carbonate (13 mg) and acetyl chloride (0.005 ml) were added to a THF/water (0.5 ml/0.5 ml) solution containing 6-((3-(1,3-dioxoisoindolin-2-yl)piperidin-4-yl)amino)-5-fluoro-2-((5-methylpyridin-3-yl)amino)nicotinonitrile (15 mg) obtained in the 2nd step under ice cooling, followed, by stirring at room temperature for 0.5 hours. Ethyl acetate was added to the reaction solution. The obtained organic layers were washed with saturated saline and dried over anhydrous sodium sulfate. Then, the solvent was distilled away under reduced pressure. Yellow oily matter of 6-((1-acetyl-3-(1,3-dioxoisoindolin-2-yl)piperidin-4-yl)amino)-5-fluoro-2-((5-methylpyridin-3-yl)amino)nicotinonitrile (12 mg) was thus obtained.
