Procedure

Phenyl isocyanate (5.4 mg, 0.045 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 (15.0 mg, 0.0303 mmol) and triethylamine (13 μL, 0.093 mmol) in N,N-dimethylformamide (0.5 mL) and methanol (0.1 mL). The reaction mixture was stirred at r.t. for 2 h. The mixture was purified by RP-HPLC (pH=10) to afford the desired product. LCMS (M+H)+: m/z=615.2.
