6-Bromo-4-[5-(chloromethyl)-1,3,4-oxadiazol-2-yl]-1-(phenylsulfonyl)-1H-indazole (300 mg, 0.661 mmol) and sodium iodide (99 mg, 0.661 mmol) were weighed into a round-bottomed flask and dissolved in acetonitrile (2 ml) before [3-(4-morpholinyl)propyl]amine (191 mg, 1.322 mmol, available from Sigma-Aldrich) and DIPEA (0.231 ml, 1.322 mmol) were added. The mixture was heated to 70° C. for 2 h, then cooled and the solvent removed under a stream of nitrogen. The crude residue was dissolved in DCM/MeOH (1:1) and preadsorbed onto silica which was then added to the top of a 20 g silica cartridge that was subsequently eluted with 0-15% MeOH(+1% triethylamine)/DCM over 20 mins. The appropriate fractions were combined and the solvent removed in vacuo to give the title compound as a yellow oily solid (328 mg).
