Dimethyl Sulfate → HCID 15341833, compound

Participants

Reaction Steps

The compound of Example 54 (132 mg, 0.280 mmol), potassium hydroxide (18.8 mg, 0.336 mmol) and dimethyl sulfate (52.9 mg, 0.420 mmol) were added to THF, and the reaction mixture was stirred overnight at room temperature, then 10 ml of water was added, and the layers were separated. The aqueous layer was extracted three times with ethyl acetate, and the combined organic fractions were dried and filtered. The solvent was removed under vacuum to give an oil. Chromatography of the oil on silica gel with 50/50 ethyl acetate/hexane gave the product as a white solid.
