실험 절차

4-[2-(acetylamino)-4-methyl-1,3-thiazol-5-yl]-5-bromothiophene-2-sulfonyl chloride, prepared as in Step III of Example 23 (300 mg; 0.72 mmol; 1 eq), is dissolved in anhydrous DCM (20 ml). The solution is put under nitrogen. Triethylamine (0.5 ml; 3.61 mmol; 5 eq) and 3-pyrrolidinol (0.3 ml; 3.61 mmol; 5 eq) are added successively. DMF (0.2 ml) is added and the reaction mixture is stirred for 1 hour at room temperature. It is then washed with water, NaHCO3 sat., brine and dried over MgSO4, affording the title compound (310 mg; 83%).
