실험 절차

2-Amino-4-[(1,1-dimethyl)ethyl]thiazole (0.87 g, 5.6 mmol) was dissolved in carbon tetrachloride (9 mL). N-Bromosuccinimide (1.00 g, 5.6 mmol) was added, and the mixture was stirred at room temperature for 1 hour. Hexane was added to the reaction mixture, the insoluble matter was filtered off, and the residue obtained by evaporation of the filtrate under reduced pressure was purified by chromatography on silica gel (hexane:ethyl acetate=2:1) to give the title compound (1.23 g, 93.7%) as a yellowish gray powder.
