1H-Imidazole-2-carboxylic acid (17 mg) (available from Maybridge), HATU (63 mg) and 6-(1H-indol-4-yl)-2-(tetrahydro-2H-pyran-2-yl)-2H-indazol-4-amine (50 mg) were dissolved in anhydrous DMF (3 ml) and then treated with DIPEA (0.052 ml) and stirred at RT for 15 h. The mixture was treated with methanol (3 ml) and then macroporous-tosic acid resin (170 mg; 4.4 mmol/g) then stirred for 15 h. The mixture was then treated with 0.88 ammonia solution (0.600 ml), stirred for 10 min, then filtered and solvent blown off under a stream of nitrogen. The crude residue was purified by mass directed preparative HPLC (Method A) to give the title compound.
