合成路线1
该中间体在本合成路线中的序号：(XVI)2) The addition of 1-(4-nitrophenyl)piperazine (I) to the chiral oxirane (XIII) as before gives the disubstituted piperazine (XIV), which is hydrogenated with H2 over Pd/C in ethyl acetate, yielding the anilino derivative (XV). The acylation of (XV) with phenyl chloroformate (V) and triethylamine in dichloromethane affords the carbamate (XVI), which is treated with hydrazine to give the semicarbazide (XVII). The cyclization of (XVII) with formamidine (VIII) as before affords the triazolone (XVIII), which is finally condensed with 4-(trifluoromethoxy)benzyl bromide (X) by means of Cs2CO3 in DMF.
