실험 절차
A resealable pressure tube was charged with 4-(6-tert-butylpyridin-2-ylamino)-6-chloropyridazine-3-carboxamide (100 mg, 327 μmol) dissolved in NMP (2.00 mL) To this solution was added tert-butyl (3R,4R)-4-aminotetrahydro-2H-pyran-3-ylcarbamate (70.7 mg, 327 μmol) and the reaction mixture was heated in an oil bath with stirring at 130° C. for 24 h. Added additional tert-butyl (3R,4R)-4-aminotetrahydro-2H-pyran-3-ylcarbamate (70.7 mg, 327 μmol) and reaction continued for 24 h. Added more tert-butyl (3R,4R)-4-aminotetrahydro-2H-pyran-3-ylcarbamate (70.7 mg, 327 μmol) and reaction continued for 72 h. The NMP was evaporated under high vacuum. The residue was purified by flash chromatography (silica gel 50 μm, 40 g, Analogix) eluting with 0 to 5% over 20 min (MeOH containing 10% NH4OH)/CH2Cl2 to yield tert-butyl (3R,4R)-4-(5-(6-tert-butylpyridin-2-ylamino)-6-carbamoylpyridazin-3-ylamino)tetrahydro-2H-pyran-3-ylcarbamate (73 mg, 46.0% yield) as a yellow foam. 1H NMR (CHLOROFORM-d) δ: 11.45 (br. s., 1H), 8.33 (s, 1H), 8.14 (s, 1H), 8.06 (d, J=3.4 Hz, 1H), 7.52 (t, J=7.9 Hz, 1H), 6.91 (d, J=7.9 Hz, 1H), 6.66 (d, J=7.9 Hz, 1H), 5.65 (br. s., 1H), 5.37 (d, J=8.3 Hz, 1H), 3.38-4.31 (m, 6H), 1.63-2.23 (m, 2H), 1.46 (s, 9H), 1.39 (s, 9H); LC-MS 486.3 [M+H]+.
