Participants

Reaction Steps

A solution of the compound of Example 95 (2.55 g, 9.2 mmole) and concentrated sulfuric acid (3 drops) in ethanol (125 mL) was heated at reflux for 80 hours. The mixture was cooled and diluted with water, and the crude product was isolated by extraction with ethyl acetate. This was chromatographed (9:1 hexane/ethyl acetate) and recrystallized (hexane) to provide the title compound (1.74 g, 62%) as white needles, mp 79°-80°.
