Reaction Steps

To the isopropyl ester from Step 7 (5.2 g, 10 mmol) in THF (30 mL), MeOH (10 mL) was added NaOH (2 g, 50 mmol) in water (10 mL). The solution is heated to 65° C. for 5 hours. The solution was cooled to room temperature, extracted with methylene chloride and dilute hydrochloric acid. The organic was dried and evaporated and the product was purified by column chromatography (0 to 60% EtOAc/hexanes) to yield ˜3.5 grams of product.
