Procedure

5-[2-(acetylamino)-4-methyl-1,3-thiazol-5-yl]thiophene-2-sulfonyl chloride, prepared as in Step II of Example 1 (280 mg; 0.84 mmol; 1 eq), is dissolved in DCM (10 ml). N,N-dimethylpropane-1,3-diamine (0.89 ml; 8.4 mmol; 10 eq) and DIEA (0.17 ml; 0.98 mmol; 3 eq) are added. After one night reaction, water (1 ml) is added and the solvents are evaporated to dryness. The crude product is re-dissolved in DCM and washed with NH4Cl saturated solution, water and dried over MgSO4. After evaporation of the solvents, crude material is precipitated in a mixture of DCM and diethyl ether, affording after filtration, Compound (10) as a white solid (105 mg; 28%).
