Reaction Steps

A resealable pressure bottle was charged with potassium carbonate (273 mg, 2.0 mmol), 1,4-dichlorophthalazine (590 mg, 3.0 mmol), piperidin-3-ol (200 mg, 2.0 mmol) and methylsulfinylmethane (10 mL, 0.2M). The vessel was sealed and the mixture stirred at 90° C. for 24 hrs. Next day the reaction was cooled to RT and diluted with 5 ml of DMSO. The solution was purified by Gilson reverse phase liquid chromatography (10% to 90% CH3CN/H2O/0.1% TFA) to afford 1-(4-chlorophthalazin-1-yl)piperidin-3-ol. MS m/z 264 [M+1]+. Calculated for C13H14ClN3O: 263.7.
