[7-(3-Methylcarbamoyl-phenyl)-imidazo-[1,2-b]-pyridazin-2-yl]-carbamic acid methyl ester (1 eq, 0.167 mmol, 55 mg) is dissolved in DMF (1 ml) at 0° C. and NBS (1.1 eq, 0.184 mmol, 33.8 mg) is added. The reaction mixture is stirred for 1 h at 0° C. and then is diluted with EtOAc. The reaction is washed with NaHCO3 and brine, dried over MgSO4, filtered and evaporated to yield [3-Bromo-7-(3-Methylcarbamoyl-phenyl)-imidazo-[1,2-b]-pyridazin-2-yl]-carbamic acid methyl ester as a brown solid which did not require further purification; [M+H]+=406
