Participants

Reaction Steps

5-[2-(acetylamino)-4-methyl-1,3-thiazol-5-yl]thiophene-2-sulfonyl chloride, prepared as in Step II of Example 1 (110 mg; 0.33 mmol; 1 eq), is dissolved in a mixture of DCM/DMF(1/1, 10 ml). N-acetylethylene diamine (168 mg; 1.65 mmol; 5 eq) and DIEA (0.17 ml; 0.98 mmol; 3 eq) are added. After 3 hours, the 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 dissolved in DCM (3 ml) and title compound precipitates with diethyl ether, affording after filtration, Compound (13) as a yellow powder (14 mg; 11%).
