Reaction Steps

To a solution of 4-(4-chloro-phenylsulfanyl)-5-methyl-2(4-pyridin-2yl-pyrimidin-2-yl)-2,4-dihydro-pyrazol-3-one (0.344 g, 0.869 mmol) in acetone (10 mL) was added potassium carbonate (ca. 3 g) and iodomethane (0.130 g, 0.912 mmol). The suspension was heated to reflux and stirred for 2 hours. The suspension was allowed to cool to room temperature, and water (100 mL) was added. The mixture was extracted with diethyl ether (50 mL), and the organic phase was washed with brine (50 mL), dried (magnesium sulfate), filtered and concentrated to afford a white solid. Flash chromatography over silica (methylene chloride/2M ammonia in methanol, two columns) provided 0.007 g (2%) of the product as a white solid. 1H NMR analysis was consistent with the assigned structure.
