Reaction Steps

To a mixture of 4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)aniline (0.20 g 0.40 mmoles) in methylene chloride (80 mL) at 0° C. was added triphosgene (0.25 mg, 0.84 mmoles) and triethylamine (3 mL). The mixture was stirred for 20 minutes at 0° C. and 4-amino pyridine (0.10 g 0.83 mmoles) was added to the reaction mixture and stirred for another 2 hours at room temperature. The solvent was evaporated and the residue was submitted to the HPLC using acetonitrile/TFA as mobile phase to give 98.2 mg (36% yield) of 1-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]-3-pyridin-4-ylurea. (M+H)=463.3.
