该中间体在本合成路线中的序号：(IV)The condensation of 2',6'-dimethoxyacetophenone (I) with diethyl oxalate (II) by means of sodium methoxide in refluxing methanol gives the dioxobutyrate (III), which is cyclized with 7-chloroquinoline-4-hydrazine (IV) in refluxing acetic acid yielding the pyrazole derivative (V). The hydrolysis of the ester group of (V) with KOH in refluxing methanol/water affords the corresponding carboxylic acid (VI), which is finally treated with SOCl2 in refluxing toluene and condensed with 2-aminoadamantane-2-carboxylic acid.
