Procedure

Methanesulfonyl chloride (2.83 mL, 36.51 mmol) in DCM (30 mL) was added dropwise to a stirred partial solution of [1-[3-(trifluoromethyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl]piperidin-4-yl]methanol (10 g, 33.19 mmol) and triethylamine (5.09 mL, 36.51 mmol) in DCM (140 mL). The reaction was stirred for 20 minutes, quenched with water (100 mL) and extracted with DCM (2×75 mL). The organic layer was dried over MgSO4, filtered and evaporated to afford a yellow solid. The crude solid was triturated with ether to give a solid which was collected by filtration and dried under vacuum to give 6-[4-(methanesulfonyloxymethyl)piperidin-1-yl]-3-(trifluoromethyl)-[1,2,4]triazolo[4,3-b]pyridazine (7.60 g, 60.4%) as a white solid.
