실험 절차

6-Bromo-4-[5-(bromomethyl)-1,3,4-oxadiazol-2-yl]-1-(phenylsulfonyl)-1H-indazole (200 mg, 0.441 mmol) in acetonitrile (2 ml) was treated with (2R,6S)-2,6-dimethyl-1-(1-methylethyl)piperazine (138 mg, 0.883 mmol, see J. Med. Chem., 1999, 42, 1123-1144 for literature preparation), DIPEA (0.154 ml, 0.8825 mmol) and sodium iodide (66 mg, 0.44 mmol). The reaction mixture was heated at 70° C. for 5 h. The reaction mixture was then cooled, diluted with DCM and washed with an aqueous 2M HCl solution (5 ml). The organic layer was separated using a hydrophobic frit, washed with water and the solvent removed under a stream of nitrogen to give the title compound as a brown oil.
