合成路线1
该中间体在本合成路线中的序号：(IV)Williamson's ether synthesis between 2-chloro-4-nitrophenol (I) and 3-fluorobenzyl bromide (II) afforded ether (III). The nitro group of (III) was then reduced to the aniline (IV) by means of catalytic hydrogenation over Pt/C. Condensation of aniline (IV) with 4-chloro-6-iodoquinazoline (V) furnished the diaryl amine (VI). Subsequent Stille coupling between iodide (VI) and 5-dioxolanyl-2-(tributylstannyl)furan (VII) gave rise to adduct (VIII), which was further subjected to acid hydrolysis of the cyclic ketal to yield aldehyde (IX). Finally, reductive amination of (IX) with 2-(methanesulfonyl)ethylamine (X) in the presence of sodium triacetoxyborohydride provided the title compound.
