Participants

Reaction Steps

The compound of Example 33 (100 mg, 0.2 mmol), dimethyl sulfate (76 mg, 0.6 mmol), and potassium hydroxide (22 mg, 0.4 mmol) were added to about 15 ml of THF. The reaction mixture was stirred overnight at room temperature then washed with water and thoroughly extracted with ethyl acetate. The organic layer was dried over magnesium sulfate and concentrated in vacuo. Chromatography of the crude material on silica gel using 50/50 ethyl acetate/hexane as eluant gave the product.
