Conditions

Temperature: -78 °C

Procedure

50 mg of 3-(4-Bromo-2-morpholin-4-yl-thiazol-5-yl)-8-(1-ethyl-propyl)-2,6-dimethyl-imidazo[1,2-b]pyridazine (0.11 mmol) is dissolved in 4 ml of diethylether and cooled to −78° C. and 0.1 ml of n-BuLi 1.6M in hexane (0.16 mmol) is added at −78° C. and stirred at −78° C. for 20 min. 104 mg of N-fluorobenzene sulfonimide (0.33 mmol) in 2 ml of toluene is added at −78° C. and stirred at room temperature for 1 h. sat. NH4Cl is added, and the mixture is extracted with Et2O, dried over Na2SO4 and evaporated. The crude product is applied onto a silica-gel chromatography column (Hexane:AcOEt=3:1) to give 4.1 mg of the title compound. Yield 10%. Mass spectrum (m/e): 404 (M+1). 6.71 (s, 1H), 3.87 (t, J=4.6 Hz, 4H), 3.55 (t, J=5.0 Hz, 4H), 3.34 (m, 1H), 2.58 (s, 3H), 2.54 (s, 3H), 1.84 (m, 4H), 0.88 (t, J=7.4 Hz, 6H).
