実験手順

1-Ethyl-3-methyl-1H-pyrazole-5-carboxylic acid (67.8 mg) was treated with N-[(dimethylamino)(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yloxy)methylidene]-N-methylmethanaminium hexafluorophosphate (168 mg) in DMF (750 μl) and DIPEA (150 μl). Reaction mixture was shaken for five min prior to treatment with 6-(1H-indol-4-yl)-1H-indazol-4-amine (50 mg) in DMF (350 μl). Reaction mixture was left to stand at 22° C. for 16 hrs. Solvent was removed in vacuo and the product re-dissolved in chloroform (0.3 ml) prior to application on to a preconditioned (methanol then chloroform) aminopropyl SPE cartridge (1 g). Product was eluted after 2 h with ethyl acetate:methanol (1:1, 3.2 ml), and concentrated under a stream of nitrogen using blow down apparatus. Purification by mass directed preparative HPLC (Method B) gave the title compound.
