実験手順

To a stirred solution of triphosgene (140 mg, 0.47 mmol) in CH2Cl2 (6 mL) was added 4-[4-(3,6-dihydro-2H-pyran-4-yl)-6-morpholin-4-yl-[1,3,5]triazin-2-yl]-phenylamine (200 mg, 0.59 mmol) at 25° C. The reaction mixture was stirred for 15 min and 4-aminopyridine (166 mg, 1.77 mmol) and NEt3 (814 μL, 5.89 mmol) were added and the reaction mixture was stirred for additional 1 hr. The solvents were distilled and the crude mixture was purified by semi-prep-HPLC (TFA-method) to give 1-{4-[4-(3,6-dihydro-2H-pyran-4-yl)-6-morpholin-4-yl-[1,3,5]triazin-2-yl]-phenyl}-3-pyridin-4-yl-urea (75 mg, 22% yield); MS (ESI) m/z 460
