Procedure

To the methyl ester from Step 5 (5.2 g, 12.4 mmol) in THF (100 mL) and ethanol (20 mL) was added a solution of sodium hydroxide (1.5 g, 37.2 mmol) in water (40 mL). The solution was stirred at room temperature 3 hours. ˜50 mL solvent evaporated and 200 mL water added. The product was precipitated out of solution with dilute hydrochloric acid to pH 2. The product was isolated by filtration to yield 4.6 grams of the title compound.
