実験手順

4-[2-(acetylamino)-4-methyl-1,3-thiazol-5-yl]-5-bromothiophene-2-sulfonyl chloride, prepared as in Step III of Example 23 (500 mg; 1.2 mmol; 1 eq), is dissolved in anhydrous DCM (30 ml). The reaction is put under nitrogen. Triethylamine (0.34 ml; 2.41 mmol; 2 eq) and 5-amino-1H-tetrazole (204.6 mg; 2.41 mmol; 2 eq) are added successively and the reaction mixture is stirred overnight at room temperature. It is then washed with water, NH4Cl sat., brine and dried over MgSO4, affording the title compound (550 mg; 64%).
