Participants

Reaction Steps

The compound of Example 44 (105 mg, 0.2153 mmol), dimethyl sulfate (40.7 mg, 0.3229 mmol) and potassium hydroxide (15 mg, 0.2583 mmol) were added to 2.0 ml of THF. The reaction mixture was stirred at room temperature overnight, and then 10 ml of water was added. The mixture was extracted three times with ethyl acetate, and the extracts were combined and dried over anhydrous magnesium sulfate then filtered, and the solvent was removed under vacuum to give an oil. Chromatography of the oil on silica gel with 50/50 ethyl acetate/hexane as eluant gave the product as a colorless gum.
