2-(Tributylstannyl)furan → 2-Chloro-4-(2-furyl)thieno[3,2-d]pyrimidine

Participants

Reaction Steps

A solution of 2,4-dichlorothieno[3,2-d]pyrimidine (205 mg, 1 mmol) in DMF (4 mL) was treated with PdCl2(PPh3)2 (35 mg, 0.05 mmol) and 2-(tributylstannyl)-furan (315 μL, 1 mmol), stirred at room temperature for 16 h, the reaction mixture purified directly by chromatography (SiO2:EtOAc:Heptane, 1:9) and the resulting cream solid recrystallised (EtOAc/Heptane) to give the title compound (122 mg, 52%) as a cream solid.
