Reaction Steps

To a solution of 4,6-dichloro-5-(p-tolyl)pyrimidine (Example 1b; 717 mg) in DMSO (5 ml) and n-propanesulfonamide potassium salt (1016 mg) was added. Stirring was continued for 14 h at rt. The solution was poured onto ice/water and acidified by 2 N HCl to pH 3-4. The precipitate was filtered off and washed with water and diethylether to give n-propanesulfonic acid (6-chloro-5-p-tolyl-pyrimidin-4-yl)-amide (765 mg) as a white powder. LC-MS: tR: 4.44, [M+H]+: 326.13.
