실험 절차
To a solution of 6-methylbenzo[d]thiazol-2-amine (109, 328 mg, 2 mmol, Sigma-Aldrich) in DMF (5 mL) was added di(1H-imidazol-1-yl)methanone (110, 357 mg, 2.2 mmol, Sigma-Aldrich) at 0° C. Under vigorous stirring, the resulting reaction mixture was slowly allowed to warm to a temperature of about 25° C. over 14 h. A white precipitate formed. The precipitate was collected by filtration under reduced pressure, washed twice with EtOAc (10 mL for each wash), and dried under reduced pressure to provide 108 (yield >99%).
