Participants

Reaction Steps

To a solution of 100 mg (0.27 mmol) of the compound obtained from Example 8 in 10 ml of anhydrous ethanol was added 20 mg of p-toluenesulfonic acid monohydrate. The reaction mixture was refluxed with stirring for about 48 hours, neutralized with sodium bicarbonate, and evaporated under reduced pressure to give a light brown residue, which was purified by flash chromatography using a mixture of ethyl acetate and hexane (1:2) as an eluent to afford 60 mg (yield 58%) of the title compound as a white solid.
