Reaction Steps

A mixture of (6-chloro-imidazo[1,2-b]pyridazin-8-yl)-pyridin-2-yl-amine (0.063 g, 0.26 mmol), 2 mL of toluene, 0.5 mL of ethanol, cyclohexen-1-yl boronic acid (0.065 g, 0.51 mmol), Pd(PPh3)4 (0.032 g, 0.027 mmol), and 0.36 mL of a 2 M aq. potassium carbonate solution under N2 was stirred at 170° C. in a microwave for 3 h. The mixture was partitioned between 10 mL of a 10% NaOH solution and 10 mL of dichloromethane. The aqueous layer was further extracted with 10 mL of dichloromethane. The combined organic layers were dried over MgSO4, filtered and concentrated to 0.093 g of a pale yellow oil. Column chromatography (0->33% EtOAc/hexanes) afforded 0.050 g (66%) of (6-cyclohex-1-enyl-imidazo[1,2-b]pyridazin-8-yl)-pyridin-2-yl-amine as a white solid.
