Procedure

14.3 mg (0.04 mmol) 1-[4-(2-Methyl-7-phenyl-3-vinyl-imidazo[1,2-b]pyridazin-6-yl)-phenyl]-cyclobutylamine, example 12, were given in five mL ethyl acetate (no complete dissolution). After addition of a catalytic amount of palladium/charcoal (10%) the reaction mixture was stirred under a hydrogen atmosphere for three hours. Due to an incomplete reaction one mL ethanol was added and stirring was continued over night. The catalyst was sucked off via a glass fibre filter and washed with ethanol. After evaporation of the solvents 11.9 mg (66.2%) of the title compound were obtained which were slightly contaminated.
