该中间体在本合成路线中的序号：(IV)Condensation of 3,4-dimethoxybenzylamine (I) with 3,4-dimethoxybenzaldehyde (II) afforded imine (III), that was subsequently reduced to amine (IV) by means of NaBH4. Reaction of (V) with 2,4,6,8-tetrachloropyridopyrimidine (V) in THF at room temperature produced the 4,8-diamino derivative (VI). The remaining 2- and 6-chloro groups of (VI) were then displaced by aminoalcohol (VII) in boiling THF to furnish adduct (VIII). Finally, selective cleavage of two dimethoxybenzyl groups using trifluoroacetic acid gave rise to the title compound.
