Versuchsvorschrift

4-[2-(acetylamino)-4-methyl-1,3-thiazol-5-yl]-5-bromothiophene-2-sulfonyl chloride, prepared as in Step III of Example 23 (136 mg; 0.33 mmol; 1 eq), is dissolved in DCM (10 ml). Morpholine (0.25 ml; 1.65 mmol; 5 eq) and DIEA (0.17 ml; 0.98 mmol; 3 eq) are added under a nitrogen atmosphere. After 3 hours, 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 flash chromatography using cyclohexane/EtOAc (1/1) as eluent, affording the expected compound as an oil (118 mg; 77%).
