실험 절차
A suspension of 3-chloro-6-(2-chlorophenyl)-7-(4-chlorophenyl)-[1,2,4]triazolo[4,3-b]pyridazine (38 mg, 0.1 mmol) in cyclohexylamine (0.5 mL) was stirred at 100° C. for 16 h. After cooling to room temperature, the reaction mixture was concentrated under reduced pressure. The residue was diluted with EtOAc (30 mL), washed with H2O, saturated aqueous NaCl, dried (Na2SO4), filtered and concentrated under reduced pressure. The crude product was purified using a silica gel cartridge (12 g) eluting with a gradient of EtOAc (40-100%) in hexanes to afford 18 mg (41%) of the title compound as a yellow powder. HPLC/MS (method A): retention time=3.58 min, (M+H)+=438.1. 1H NMR (CDCl3, 400 MHz): δ 7.87 (s, 1H), 7.35-7.43 (m, 3H), 7.30-7.33 (m, 1H), 7.20 (d, J=8.56 Hz, 2H), 7.04 (d, J=8.31Hz, 2H), 4.83 (s, 1H), 3.98 (s, 1H), 2.22-2.25 (m, 2H), 1.79 (dd, J=9.78, 3.67 Hz, 2H), 1.63-1.72 (m, 1H), 1.41-1.52 (m, 2H), 1.27-1.39 (m, 2H), 1.21-1.26 (m, 1H).
