실험 절차

To a −78° C. solution of 3-[3-chloro-5-(2-methyl-2H-[1,2,4]triazol-3-yl)-thiophen-2-yl]-8-(1-ethyl-propyl)-2,6-dimethyl-imidazo[1,2-b]pyridazine (0.30 g, 0.72 mmol) and THF (5 mL) is added 1.7 M tert-BuLi (0.47 mL, 0.80 mmol). After 15 minutes MeI (0.052 mL, 0.83 mmol) is added and the solution warmed to ambient temperature. The solution is diluted with EtOAc (40 mL), washed with brine (40 mL), dried over MgSO4, filtered and concentrated. The solution is recrystallized from acetone:hexane furnish the title compound (0.13 g, 0.30 mmol, 42%). 1H NMR (CDCl3) δ0.88 (t, J=7.5 Hz, 6H), 1.74-1.92 (m, 4H), 2.36 (s, 3H), 2.51 (s, 6H), 3.27-3.39 (m, 1H), 3.40 (s, 3H), 6.72 (s, 1H), 8.02 (s, 1H). LC/MS (m/z): calcd. for C21H25ClN6S (M+H)+: 429.2; found: 429.2.
