HCID 31374DimethylacetamideSolvent

Procedure

0.13 ml of propionyl chloride is added slowly dropwise to a solution of 0.64 g of 5-amino-N-[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-2-dimethylaminocarbonylbenzenesulfonamide in 10 ml of dimethylacetamide. After the end of reaction, the reaction mixture is concentrated under reduced pressure and the residue is washed with water and ethyl acetate, to give 0.45 g of the desired product in high purity (>92%, HPLC).
