Procedure

To a solution of 3-(2-fluorophenyl)-[1,2,4]triazolo[4,3-b]pyridazine-6-thiol (1 mmol) and cesium carbonate (1.5 equiv.) in DMF (5 mL) was added 2-bromo-1-(piperidin-1-yl)butan-1-one (1.5 equiv.) and the mixture was stirred at 70° C. for 3 hours. The reaction was monitored by thin-layer chromatography and was shown to be complete at this time. The solvent was removed in vacuo and the residue was flash chromatographed to give 2-((3-(2-fluorophenyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)thio)-1-(piperidin-1-yl)butan-1-one.
