5-Methyl-1H-pyrazole-3-carboxylic acid (10 mg) in DMF (0.2 ml) was treated with N-[(dimethylamino)(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yloxy)methylidene]-N-methylmethanaminium hexafluorophosphate (27 mg) in DMF (0.2 ml) and DIPEA (0.03 ml). The reaction mixture was shaken for five min prior to treatment with 6-(1H-indol-4-yl)-2-(tetrahydro-2H-pyran-2-yl)-2H-indazol-4-amine (20 mg) in DMF (0.2 ml). The reaction mixture was shaken for five min and left to stand at 22° C. for 18 h. The solvent was removed in vacuo and the product re-dissolved in methanol (1 ml) prior to application on to an SCX SPE cartridge (1 g). The product was eluted after 1 h with 2M ammonia in methanol (2×3 ml), the fractions were combined and concentrated under a stream of nitrogen using blow down apparatus. Purification by mass directed preparative HPLC (Method C) afforded the title compound.
