실험 절차

To a solution of tert-butyl (1S,2R)-2-(6-carbamoyl-5-(6-(2-cyanopropan-2-yl)pyridin-2-ylamino)pyridazin-3-ylamino)cyclohexylcarbamate (110 mg, 222 μmol) in CH2Cl2 (3.00 mL) was added TFA (1.48 g, 1.00 mL, 13.0 mmol) and the reaction mixture stirred to room temperature for 18 h. Solvents evaporated and residue purified by flash column (spherical silica 20-45 μM, 23 g, Versaflash Supelco) eluting with 0 to 5% over 20 min (MeOH containing 10% NH4OH)/CH2Cl2 to give 6-((1R,2S)-2-aminocyclohexylamino)-4-(6-(2-cyanopropan-2-yl)pyridin-2-ylamino)pyridazine-3-carboxamide (50 mg, 57% yield) as an off-white solid. 1H NMR (CHLOROFORM-d) δ: 11.47 (s, 1H), 8.76 (s, 1H), 8.06 (d, J=3.0 Hz, 1H), 7.60 (t, J=7.9 Hz, 1H), 6.86 (d, J=7.6 Hz, 1H), 6.78 (d, J=7.9 Hz, 1H), 5.60-5.77 (m, 2H), 4.25 (br. s., 1H), 3.11-3.24 (m, 1H), 1.32-1.92 (m, 16H); LC-MS 395.1 [M+H]+.
