YieldReaction ConditionsOperation in experiment
72% 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.
Lithium diisopropylamide (1.8 M in THF, 19.8 mL, 35.6 mmol) was added dropwise to a stirred solution of <strong>[405939-39-1](5-bromo-thiazol-2-yl)-carbamic acid tert-butyl ester</strong> (Kuo, Gee-Hong; et al. J. Med. Chem. 2005; 6; 1886 - 1900) (3.00 g, 10.8 mmol) in anhydrous THF (75 mL) at00C. After stirring for 30 min at 0C, a solution of 1,1,1,2,2,2-hexachloro-ethane (8.43 g, 35.6 mmol) in anhydrous THF (45 mL) was added dropwise at -900C. The reaction mixture was allowed to warm to -10C and was then quenched by the addition of concentrated aqueous NH4CI (15 mL). The mixture was concentrated in vacuo and the residue was partitioned between DCM (100 mL) and water (30 mL). The aqueous layer was extracted with DCM (2 x50 mL) and the combined organic layers were dried over Na2SO4, filtered, and concentrated in vacuo. The residue was purified by flash chromatography on silica gel (elution withDCM/hexane 2:1) to give the title compound. MS (m/z): 314.6 [IVB-H+].
