Versuchsvorschrift
2-Acetoxy-5-bromo-N-{4-[(1,1-dimethyl)ethyl]thiazol-2-yl}benzamide (compound of Example 181(2); 0.20 g, 0.50 mmol) was dissolved in acetonitrile (10 mL). N-Bromosuccinimide (97.9 mg, 0.55 mmol) was added, and the mixture was stirred at room temperature for 1 hour. The reaction mixture was concentrated under reduced pressure, and the obtained residue was purified by chromatography on silica gel (n-hexane:ethyl acetate=3:1) to give the title compound as a crude product.
