Procedure
To a solution of methyl imidazo[1,2-b]pyridazine-6-carboxylate (1-3) (891 mg, 5.03 mmol) in ethanol (25 mL) was added NaBH4 (420 mg, 11.1 mmol) at room temperature. The suspension was stirred at room temperature for 2 h. The reaction mixture was concentrated in vacuum. The residue was purified by chromatography on silica gel to afford the title compound (630 mg). MS (m/z): 150 (M+1)+
