To a solution of N-(4-{1-ethyl-4-[2-(1,2,3,6-tetrahydro-4-pyridinyl)-1H-pyrrolo[2,3-b]pyridin-4-yl]-1H-pyrazol-3-yl}phenyl)-N′-phenylurea (0.23 mmol) was in N,N-dimethylformamide (3.0 mL) was added EDC (0.39 mmol), HOBt (0.39 mmol), triethylamine (1.38 mmol) followed by N,N dimethylglycine (0.39 mmol). The reaction stirred at room temp for 16 h. The reaction was poured into ethyl acetate and washed saturated sodium bicarbonate (2×10 mL). The organic layer was evaporated and purification of the residue by Gilson reverse phase HPLC provided the title product. ESMS [M+H]+: 589.4
