Reaction Steps

370 mg of 3-(2-Bromo-4-methyl-thiazol-5-yl)-8-(1-ethyl-propyl)-2,6-dimethyl-imidazo[1,2-b]pyridazine (0.93 mmol) is dissolved in 10 ml of dry THF and cooled to −78° C. 0.6 ml of n-BuLi 2.0 M in hexane (1.2 mmol) is added and stirred at −78° C. for 30 min. 141 mg of tetrahydro-4H-pyran-4-one (1.41 mmol) is added and stirred at −78° C. for 2 h. The reaction mixture is diluted with AcOEt, washed with sat. NH4Cl, dried over Na2SO4 and evaporated. The crude product is applied onto a silica-gel chromatography column (Hexane:AcOEt:2 M NH3 in MeOH=10:3:1) to give 152 mg of the title compound. Yield 40%: mass spectrum (m/e): 415 (M+1). 1H NMR (CDCl3): δ 6.74 (s, 1H), 3.99 (t, J=2.2 Hz, 4H), 3.97 (t, J=2.2 Hz, 4H), 3.35 (m, 1H), 3.20 (s, OH), 2.56 (s, 3H), 2.48 (s, 3H), 2.36 (s, 3H), 1.88 (m, 4H), 0.91 (t, J=7.3 Hz, 6H).
