合成路线1
该中间体在本合成路线中的序号：(II)Alkylation of 5,6-diphenyl-2-pyrazinol (I) with mesylate derivative (II) furnishes the pyrazinyl ether (III). The aldehyde function of (III) is then reduced to alcohol (IV) employing NaBH4 in EtOH. Chlorination of alcohol (IV) by means of SOCl2 in the presence of catalytic DMF leads to the benzyl chloride (V). This is finally condensed with imidazole (VI) in hot DMF to yield the title compound
