実験手順

A mixture of 3-chloro-4-(2-hydroxyethylamino)-N-(3-hydroxy-4-methyl-phenyl)-benzamide (34.2 mg, 0.11 mmol) and potassium carbonate (17.3 mg, 0.123 mmol) was stirred at room temperature for 30 minutes before 3-bromomethyl-4-chloro-1-methyl-1H-pyrazolo[3,4-d]pyrimidine (25.4 mg, 0.097 mmole, Example 5) was added. The reaction was stirred at room temperature overnight and then concentrated under reduced pressure to remove dimethylformamide. The residue was dissolved in ethyl acetate, washed with water, dried and concentrated. The crude product was either used directly in the next step (described in Example 9) or purified by flash chromatography (silica gel, hexanes-ethyl acetate, 90/10 to 60/40) to give pure 3-chloro-N-[3-(4-chloro-1-methyl-1H-pyrazolo[3,4-d]pyrimidin-3-ylmethoxy)-4-methyl-phenyl]-4-(2-hydroxy-ethylamino)-benzamide as a white solid. (Yield 22 mg).
