To a solution of HATU (0.107 g, 0.28 mmol) in dry DMF (3 ml) was added 4-acetyl-2-morpholinecarboxylic acid (0.05 g, 0.282 mmol). DIPEA (0.098 ml, 0.56 mmol) was added and the mixture was left to stand for 10 min. 6-(1H-indol-4-yl)-1H-indazol-4-amine (0.04 g, 0.14 mmol), dissolved in dry DMF (3 ml) was added and the solution was left to stand at room temperature for 20 hr. DMF was removed by blow down under a stream of nitrogen, then the residue was dissolved and purified by Mass Directed AutoPrep Method B. The solvent was removed in vacuo and product dried in a vacuum oven at 50° C. overnight to give the title compound as a brown oil (17 mg).
