Reaction Steps

A solution of N-(3,4-dimethoxybenzyl)-4-(2-furyl)thieno[3,2-d]pyrimidine-2-amine (199 mg, 0.54 mmol) in TFA (1 mL) was heated at 60° C. for 1 h, cooled, poured into sat. NaHCO3, extracted with EtOAc, dried (MgSO4), concentrated in vacuo and purified by chromatography (SiO2:EtOAc:Heptane, 1:1 and MeOH:DCM, 1:19) to give the title compound (108 mg, 92%) as a cream solid.
