Versuchsvorschrift

4-[2-(Acetylamino)-4-methyl-1,3-thiazol-5-yl]-5-bromothiophene-2-sulfonylchloride, prepared as in Step III of Example 23 (100 mg; 0.229 mmol; 1 eq) is dissolved in DCM (10 ml). Allyl amine (0.15 ml; 1.14 mmol; 5 eq) and DIEA (0.17 ml; 0.70 mmol; 3 eq) are added under a nitrogen atmosphere. After 2 hours reaction, solvents are evaporated. The crude product is dissolved in DCM and washed with NH4Cl saturated solution, water and dried over MgSO4. After evaporation of the solvents, crude material is purified by reverse preparative HPLC, affording N-(5-{5-[(allylamino)sulfonyl]-2-bromo-3-thienyl}-4-methyl-1,3-thiazol-2-yl)acetamide as a white solid (35 mg; 35%).
