Reaction Steps

To a solution of 2-[8-(1-ethyl-propyl)-2,6-dimethyl-imidazo[1,2-b]pyridazin-3-yl]-thiophene-3-carbonitrile (0.83 g, 2.56 mmol) and CH2Cl2 (10 mL) is added NBS (0.48 g, 2.69 mmol). The solution is stirred for 1 hour, diluted with Et2O (100 mL), washed with water (3×100 mL), brine (100 mL), dried (MgSO4) filtered and concentrated to furnish the title compound (1.03 g, 2.55 mmol, >99%). 1H NMR (CDCl3) δ 0.86 (t, J=7.5 Hz, 6H), 1.74-1.91 (m, 4H), 2.56 (s, 3H), 2.60 (s, 3H), 3.24-3.32 (m, 1H), 6.76 (s, 1H), 7.30 (s, 1H). LC/MS (m/z): calcd. for C18H19BrN4S (M+H)+: 404.4; found: 404.1.
