Procedure

4-[2-(acetylamino)-4-methyl-1,3-thiazol-5-yl]-5-bromothiophene-2-sulfonyl chloride, prepared as in Step III of Example 23 (300 mg; 0.72 mmol; 1 eq), is dissolved in anhydrous DCM (20 ml). The reaction mixture is put under nitrogen. Triethylamine (0.5 ml; 3.61 mmol; 5 eq) and methyl-piperidine-4-yl-carbamic acid tert-butyl ester (773.2 mg; 3.61 mmol; 5 eq) are added successively and the reaction mixture is stirred for 30 minutes at room temperature. It is then washed with water, NaHCO3 sat., brine and dried over MgSO4, affording the title compound (470 mg; quantitative).
