실험 절차

A stirred solution of 4-chloro-1-(2-fluorobenzyl)-1H-pyrazolo[3,4-d]pyrimidine-6-amine (139 mg, 0.5 mmol) in dry THF (10 mL) was treated with 2-thiopheneboronic acid (128 mg, 1.0 mmol), Pd(PPh3)4 (50 mg, 10 mol %) and saturated aqueous NaHCO3 solution (2 mL), refluxed for 30 min, diluted with H2O, extracted with EtOAc, dried (MgSO4) and concentrated in vacuo. The resulting dark brown oil was purified by chromatography [SiO2; heptane:EtOAc (1:1) then (1:3)] to give the title compound (32 mg, 20%) as a cream solid.
