Procedure

3-Tert-butyl-1-(3-fluorophenyl)-1H-pyrazole-5-carboxylic acid (393 mg, 1.5 mmol) was dissolved in dry DMF (8 mL), and triethylamine (209 μL, 1.5 mmol) was added. The solution was cooled at 0° C., and diphenylphosphoryl azide (323 μL, 1.5 mmol) was added. The reaction mixture was stirred for 30 minutes at 0° C., followed by 1 hour at room temperature. 7-(4-Amino-3-fluorophenoxy)-1-N-thyl-1H-imidazo[4,5-b]pyridin-2(3H)-one (8a) (140 mg, 0.5 mmol) was added, and the reaction mixture heated at 110° C. for 1 hour. The solution was cooled, diluted with AcOEt (100 mL) and extracted with water and brine. The organic layer was dried and evaporated, and the residue taken up in DCM. The remaining solid was recovered by filtration to afford the title compound.
