Procedure
The product of Example 94 Part A (3.0 g, 0.012 mole) was added in portions to concentrated sulfuric acid (10 ml) at -10°. The mixture was stirred at -10° for 2 hours and poured into water. Sodium bicarbonate (1.0 g) was added, and the crude product was isolated by extraction with ethyl acetate. The title compound (2.0 g, 52%) was obtained as a brown oil after chromatography (1:1 hexane/ethyl acetate; then 99:1 ethyl acetate/acetic acid; then methanol).
