Versuchsvorschrift

A solution of 5-(2-methylsulfanyl-pyrimidin-4-yl)-thiophene-2-sulfonyl chloride (200 mg, 0.652 mmol) in 6 mL DCM was treated with pyridine (0.078 mL, 0.97 mmol) and 2 M dimethylamine/THF (0.485 mL, 0.97 mmol). The solution was stirred overnight. Additional 2 M dimethylamine/THF (0.400 mL, 0.8 mmol) was added and the reaction was stirred overnight. The mixture contained <5% starting material by LCMS. The mixture was washed 2×1 N HCl, 1× brine and dried over Na2SO4. 5-(2-Methylsulfanyl-pyrimidin-4-yl)-thiophene-2-sulfonic acid dimethylamide (154 mg, 74.9%) was obtained as an off-white solid, >95% pure by LCMS. This material was taken to the next step. MS: m/z 316 (M+H+).
