Procedure
2-Methanesulfonyl-4-(2-methyl-pyridin-4-yl)-pyrimidine (720 mg, 2.89 mmol) was dissolved in dioxane (25 ml) and then 2N NaOHaq (14.4 ml, 28.9 mmol) was added. After stirring at room temperature for 2 hours, the solution was acidified with 37% HClaq. The mixture was evaporated and the residue was re-dissolved in DCM-MeOH—NH4OH (90-10-1) and evaporated. The crude was purified by flash chromatography with DCM-MeOH (9-1) to give 279 mg of the title compound. (52% yield).
