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 (1900 mg; 4.57 mmol; 1 eq), is dissolved in anhydrous DCM (180 ml). The reaction is put under nitrogen. Triethylamine (3.2 ml; 22.9 mmol; 5 eq) and ethanolamine (1.1 ml; 18.3 mmol; 4 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 (1760 mg; 88%).
