405939-39-1, tert-Butyl (5-bromothiazol-2-yl)carbamate is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,405939-39-1
To a solution of tert-butyl N-(5-bromo-l,3-thiazol-2-yl)carbamate (5 g, 17.9 mmol) in tetrahydrofuran (100 ml) was added dropwise LDA (29.4 ml, 2 mol/L) at -78 C, and the resulting mixture was stirred for 1 h at -78C. Then the mixture was added a solution of hexachloroethane (14 g, 59.1 mmol) in tetrahydrofuran (50 ml) at -78 C. The reaction was stirred for additional 15 h at room temperature. The reaction was quenched by water, then extracted with dichloromethane and concentrated in vacuo. The residue was purified by flash chromatography on silica gel eluting with ethyl acetate/petroleum ether (1/9) to afford tert-butyl N-(4-bromo-5-chloro-l,3-thiazol-2-yl)carbamate (4.07 g , 72%) as brown oil. LCMS (ESI): M+H+ = 313.0.
As the paragraph descriping shows that 405939-39-1 is playing an increasingly important role.
