Versuchsvorschrift
(R)-(2-Chloro-6-(3-methylmorpholino)pyrimidin-4-yl)methyl methanesulfonate (80 g, 248.62 mmol) and lithium iodide (83 g, 621.54 mmol) were dissolved in dioxane (300 ml) and then heated at 107° C. for 1 hour. The reaction mixture was quenched with water (250 ml), extracted with EtOAc (3×250 ml), the organic layer was dried over MgSO4, filtered and evaporated. The residue was dissolved in DCM and Et2O was added, the mixture was passed through silica (4 inches) and eluted with Et2O. Fractions containing product were evaporated and the residue was then triturated with Et2O to give a solid which was collected by filtration and dried under vacuum to afford (R)-4-(2-chloro-6-(iodomethyl)pyrimidin-4-yl)-3-methylmorpholine (75 g, 86%); m/z: (ESI+) MH+, 354.27.
