実験手順

3,6-Dichloropyridazine (0.2 mmol) was added to a mixture of 4-(4-methanesulfonyl-phenoxy)-1-piperidin-4-yl-1H-pyrazolo[3,4-d]pyrimidine trifluoroacetate salt (Intermediate 27; 75 mg, 0.15 mmol) and potassium carbonate (69 mg, 0.5 mmol) in dimethylformamide (1 mL). The mixture was heated to 60° C. overnight and then poured into saturated aqueous ammonium chloride solution. This mixture was extracted three times with ethyl acetate. The combined organic phases were washed twice with water and once with brine, dried (magnesium sulfate), filtered, evaporated, and purified on a silica gel column, eluting with ethyl acetate, to give 1-[1-(6-Chloro-pyridazin-3-yl)-piperidin-4-yl]-4-(4-methanesulfonyl-phenoxy)-1H-pyrazolo[3,4-d]pyrimidine (0.5 mg, 0.7%) as a white powder.
