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 (200 mg; 0.48 mmol; 1 eq), is dissolved in anhydrous DCM (10 ml). The reaction mixture is cooled down to 0° C. and put under nitrogen. Triethylamine (0.33 ml; 2.41 mmol; 5 eq) and N,N-dimethyl-1,3-propanediamine (0.3 ml; 2.41 mmol; 5 eq) are added successively and the reaction mixture is stirred at 0° C. for 1 hour. It is then washed with water, NaHCO3 and dried over MgSO4, affording the title compound (200 mg; 86%).
