Reaction Steps

A suspension of 3-(3-aminobenzyl)-7-(2-furyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine-5-amine (200 mg, 0.65 mmol) and 4A molecular sieves in THF (10 mL) was treated with 4-fluorobenzaldehyde (0.04 mL, 0.37 mmol), heated to 40° C. for 3 h, cooled to room temperature, treated sodium triacetoxyborohydride (400 mg, 1.89 mmol) and acetic acid (0.1 mL) and stirred for 15 minutes. The reaction was quenched by addition of sat. NaHCO3 (5 mL), extracted with EtOAc (2×5 mL) and the combined organic phase dried (MgSO4), concentrated in vacuo and purified by chromatography [(SiO2; EtOAc:Heptane (1:2)] to give the title compound (60 mg, 44%) as a white solid.
