Procedure

4-[2-(acetylamino)-4-methyl-1,3-thiazol-5-yl]-5-bromothiophene-2-sulfonyl chloride, prepared as in Step III of Example 23 (4200 mg; 10.1 mmol; 1 eq), is dissolved in anhydrous DCM (200 ml). The reaction is put under nitrogen. Triethylamine (7.0 ml; 50.5 mmol; 5 eq) and 1-methylpiperazine (5.61 ml; 50.5 mmol; 5 eq) are added successively and the reaction mixture is stirred for 3 hours at room temperature. It is washed with water, NH4Cl sat, brine and dried over MgSO4, affording the title compound (4200 mg; 87%).
