Reaction Steps

To a solution of 3,4,6-trichloro-pyridazine (59) (364 mg, 2 mmol) and piperidin-4-yl-methanol (35) (253 mg, 2.2 mmol) in DMSO (5 mL) was added Et3N (404 mg, 4 mmol). The reaction mixture was stirred at 100° C. overnight. The reaction mixture was diluted with water, extracted with EtOAc (30 mL×3). The combined organic extracts were washed with water (30 mL) and brine (30 mL), dried over Na2SO4 and filtered. The filtrate was evaporated in vacuo and the residue was purified by flash column chromatography on silica gel to give [1-(3,6-dichloro-pyridazin-4-yl)-piperidin-4-yl]-methanol (60) (292.3 mg, 1.12 mmol, yield 75.99%).
