合成路线1
该中间体在本合成路线中的序号：(II)The condensation of cyclohexanecarbonyl chloride (I) with 3-fluorobenzyl bromide (II) by means of tetrakis(triphenylphosphine)palladium and Zn in dimethoxyethane gives the ethanone (III), which is treated with lead tetraacetate in acetic acid, yielding the alpha-acetoxyethanone (IV). The cyclization of (IV) with ammonium acetate in refluxing acetic acid affords the oxazole derivative (V), which is treated with chlorosulfonic acid at 100 C, yielding the 4-chlorosulfonyl derivative (VI). Finally, this compound is amidated with ammonia in THF/water.

合成路线2
该中间体在本合成路线中的序号：(II)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.
