An 8-mL vial is charged with N-[5-(6-aminoimidazo[2,1-f]pyridazin-2-yl)-2-methyl-phenyl]-2,2-dimethyl-propanamide (0.097 g, 0.3 mmol), 3-bromobenzoyl chloride (0.059 mL, 0.45 mmol), pyridine (0.073 mL), and MeCN (1.0 mL). The mixture is stirred at room temperature for 16 hours, concentrated onto celite and purified by silica gel chromatography (0-100% 1:0.1 EtOAc:MeOH in CH2Cl2) to give the title compound (0.065 g). LCMS (m/z)=506.4 and 508.4 [M+H]+, tR=2.96 min.
