Reaction Steps

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 (0.27 ml; 1.92 mmol; 4 eq) and 1-methyl-piperidin-4-ylamine (0.11 ml; 0.96 mmol; 2 eq) are added successively and the reaction mixture is stirred at 0° C. for 40 minutes. It is then washed with water, NaHCO3 and dried over MgSO4, affording the title compound (185 mg; 74%).
