To a solution of 4-hydroxy-1-{[(phenylmethyl)oxy]carbonyl}-3-pyrrolidinecarboxylic acid (available from Fluorochem, 59 mg, 0.22 mmol) in DMF (1 ml) was added HATU (85 mg, 0.22 mmol) and the mixture stirred for 10 mins. Then 6-(1H-indol-4-yl)-1H-indazol-4-amine (46 mg, 0.19 mmol) and DIPEA (0.065 ml, 0.37 mmol) were added and the mixture allowed to stand for 18 h at 20° C. The solvent was removed under a stream of nitrogen and the residue purified by Mass Directed Automated Preparative HPLC (Method E), to give the title compound (6 mg) as a brown solid.
