Cyanoacetic acid (3.1 mg, 0.036 mmol) was added to a mixture of N-[3-(7-{1-[3-(cyanomethyl)azetidin-3-yl]-1H-pyrazol-4-yl}imidazo[1,2-b]pyridazin-3-yl)phenyl]-N′-(2,2,2-trifluoroethyl)urea (11.9 mg, 0.0241 mmol) and benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (16 mg, 0.036 mmol) in N,N-dimethylformamide (0.6 mL), followed by triethylamine (10. μL, 0.072 mmol). The reaction mixture was stirred at r.t. for 1 h. The mixture was purified by RP-HPLC (pH=10) to afford the desired product. LCMS (M+H)+: m/z=563.2.
