Reaction Conditions:
at 20; for 18 h;
Steps:
10.1 Step 1: 6-Methoxyimidazo[1,2-b]pyridazine 46
Sodium methoxide (7.35 eq., 7.76g, 143.6 mmol) was added to a solution of 6-chloroimidazo[1 ,2-bb]pyridazine ( 3.0 g, 19.54 mmol) in anhydrous methanol (8 ml) at ambient temperature and the reaction mixture stirred for 18 hours. The volatiles were removed by evaporation and the yellow oily residue was dissolved in dichloromethane (100 ml). The solution was washed with water (5x100 ml) until aqueous wash became neutral. The organic solution was dried (MgSC ) and the solvent removed. The title compound (m = 8.87 g, yield = 91%) was obtained as a white solid. 1H NMR (400 MHz, DMSO -cfe) d 7.36 (d, J = 9.3 Hz , 1 H), 6.85 (d, J = 9.3 Hz, 1 H), 6.61 (s, 1 H)13C NMR (101 MHz, CDCIs) d 160.2, 137.3, 132.4, 127.3, 116.8, 112.1 , 54.4
