Reaction Steps

To a stirred solution of triphosgene (60 mg, 0.20 mmol) in CH2Cl2 (3 mL) was added 4-[4-(8-Methyl-8-aza-bicyclo[3.2.1]oct-3-yloxy)-6-morpholin-4-yl-[1,3,5]triazin-2-yl]-phenylamine (100 mg, 0.25 mmol) at 25° C. The reaction mixture was stirred for 15 min and 4-aminopyridine (70 mg, 0.75 mmol) and NEt3 (346 μL, 2.5 mmol) were added and the reaction mixture was stirred for additional 1 hr. The solvents were removed and the crude mixture was purified by semi-prep-HPLC(NH3-method) to give 1-{4-[4-(8-methyl-8-aza-bicyclo[3.2.1]oct-3-yloxy)-6-morpholin-4-yl-[1,3,5]triazin-2-yl]-phenyl}-3-pyridin-4-yl-urea (28 mg, 22% yield); MS (ESI) m/z 517.
