N-(2-Chloro-5-{4-[5-(chloromethyl)-1,3,4-oxadiazol-2-yl]-1-[(4-methylphenyl)sulfonyl]-1H-indazol-6-yl}-3-pyridinyl)methanesulfonamide (25 mg, 0.042 mmol) and 1-(1-methylethyl)piperazine (500 mg, 3.90 mmol) were placed a vial and heated in a microwave at 90° C. for 15 mins. The 1-(1-methylethyl)piperazine was blown off under a stream of nitrogen and the residue suspended in isopropanol (2 ml) and 2M sodium hydroxide (1 ml) added. The mixture was stirred at room temperature for 2 h. The solvent was blown off under a stream of nitrogen and the residue purified by Mass Directed Automated Preparative HPLC (Method B) to give the title compound as a pale yellow gum (4 mg).
