A solution of 4-chloro-1-methyl-1H-pyrazole-5-carboxylic acid (available from Fluorochem) (50 mg) in dry DCM (10 ml) was treated with 1-chloro-N,N,2-trimethyl-1-propen-1-amine (0.041 ml) (available from Acros) and allowed to stir at 20° C. for 10 min when a solution of 6-(1H-indol-4-yl)-1H-indazol-4-amine (77 mg) and triethylamine (0.043 ml) in DCM (5 ml) was added and the mixture stirred at 20° C. for 18 h. The mixture was poured onto an aminopropyl SPE cartridge (1 g) and allowed to stand for 2 h, then the mixture was eluted with methanol (5 ml) and blown to dryness under a stream of nitrogen. The crude product was purified by mass directed preparative HPLC (Method A) to give the title compound as a white solid (15 mg).
