合成路线2
该中间体在本合成路线中的序号:(IX)Dioxopiperazine (X) was diacetylated in refluxing acetic anhydride to yield (XI). Aldol condensation of (XI) with the precursor aldehyde (VI) using potassium tert-butoxide in THF gave the mono-arylidene piperazine (XII). Further condensation of (XII) with the intermediate aldehyde (IX) in the presence of Cs2CO3 in DMF furnished the deacetylated bis-arylidene piperazine (XIII). The methyl ester group of (XIII) was finally hydrolyzed to the title carboxylic acid using NaOH in H2O/MeOH/THF.
