A mixture comprising [4-[3-(2-Chloro-pyridin-4-yl)-imidazo[1,2-a]pyridin-6-ylamino]-cyclohexanol (Example 2.1) (1 eq, 0.29 mmol, 100 mg), pyrazole (5 eq, 1.45 mmol, 99 mg) and cesium carbonate (3 eq, 0.87 mmol, 284 mg) in DMF (25 ml) is heated using microwave radiation at 145° C. for 6 hours. After cooling to room temperature, the mixture is loaded onto a SCX-2 cartridge eluting with MeOH followed by 2M NH3 in MeOH. The solvent is removed in vacuo and the crude product is triturated with ethyl acetate to afford the title compound; [M+H]+=375
