실험 절차
Using analogous reagents and reaction conditions as described in Example 24 for the preparation of I-24a above, 3-bromo-4-fluoro-benzenethiol (2.0 g, 9.756 mmol) was reacted with 1-chloro-propan-2-one (0.86 mL, 10.73 mmol), DMF (6.0 mL), and potassium carbonate (2.69 g, 19.51 mmol) to afford crude product which was purified by column on silica gel (5% ethyl acetate in hexane) to afford 2.1 g of the product (82% yield).
