合成路线1
Lithiation of 1,3-bis(O-methoxymethyl)resorcinol (I) by means of n-butyllithium, followed by acylation with acetyl chloride, gave the protected acetophenone (II). Subsequent acid hydrolysis of the methoxymethyl protecting groups furnished diol (III). The 4-hydroxybenzofuran derivative (VI) was prepared by monoalkylation of (III) with ethyl bromoacetate (IV), followed by base-catalyzed cyclization of the resulting keto ester (V). Alkylation of the hydroxybenzofuran (VI) with 1,3-dibromopropane (VII) gave the bromopropyl ether (VIII). This was finally condensed with 3-picolylamine (IX) to produce the title compound.
