실험 절차
Using analogous reagents and reaction conditions as described in Example 25 for the preparation of I-25b above, 6-bromo-4-fluoro-benzo[b]thiophene-2-carboxylic acid methyl ester (I-26b: 2.3 g, 7.85 mmol) in THF (25 mL) was hydrolyzed with LiOH (1.65 g, 39.38 mmol) and water (20 mL) to afford 1.9 g of the product (83% yield).
