Procedure

4-[2-(1-piperazinyl)ethyl]morpholine (14.1 mg, 0.11 mmol) and 4-[5-(chloromethyl)-1,3,4-oxadiazol-2-yl]-6-(1H-indol-4-yl)-1-(phenylsulfonyl)-1H-indazole (50 mg, 0.102 mmol) were dissolved in acetonitrile (0.5 ml) and N,N-diisopropylethylamine (0.026 ml, 0.15 mmol) was added, followed by sodium iodide (15.3 mg, 0.102 mmol). The solution was stirred at 70° C. for 18 h and blown to dryness under a stream of nitrogen. Isopropanol (0.3 ml) was added followed by 2M sodium hydroxide (0.3 ml) and stirred for 5 h when the mixture was neutralised and the solvent removed under a stream of nitrogen. The crude product was dissolved in dimethylsulphoxide (0.3 ml) and methanol (0.15 ml) with formic acid (0.05 ml) then purified by Mass Directed Automated Preparative HPLC (Method F) to give the title compound (26.4 mg).
