N,N-Dimethylcarbamoyl chloride (0.24 g, 2.23 mmol) was added to a solution of 2-[(2S)-2-(4-aminophenyl)morpholin-4-yl]-3-methyl-6-(pyridin-4-yl)-pyrimidin-4(3H)-one (0.40 g, 1.10 mmol) and triethylamine (1.1 g, 10.9 mmol) in tetrahydrofuran (20 ml) and the solution was stirred at 50° C. for 48 hours. The mixture was partitioned between water and chloroform. The organic layer was washed with brine, dried over magnesium sulfate and concentrated in vacuo. The residue was purified by silica gel chromatography eluting 5-10% methanol in chloroform to furnish 1,1-Dimethyl-3-{4-[4-(1-methyl-6-oxo-4-pyridin-4-yl-1,6-dihydro-pyrimidin-2-yl) morpholin-2-yl]-phenyl}-urea (0.14 g, 30%) as white crystals.
