合成路线1
Nitrosation of tert-butyl acetoacetate (I) with NaNO2/AcOH produces the oximino ester (II). Reductive cyclization of (II) with ethyl acetoacetate (III) in the presence of Zn/AcOH leads to the pyrrole dicarboxylate (IV). Selective decarboxylation of the t-butyl ester of (IV) under acidic conditions, followed by Vilsmeier formylation of the intermediate ethyl 2,4-dimethylpyrrole-3-carboxylate furnishes the pyrrole aldehyde (V). Alternatively, this compound is directly obtained from (IV) upon treatment with trimethyl orthoformate and trifluoroacetic acid. Basic hydrolysis of the ethyl ester group of (V) yields the pyrrolecarboxylic acid (VI). This is coupled to 2-(diethylamino)ethylamine (VII) to afford the corresponding amide (VIII).

合成路线2
5-Fluoroisatin (IX) is heated with neat hydrazine hydrate to produce 2-amino-5-fluorophenylacetic hydrazide (X), which, upon acidic treatment cyclizes to 5-fluorooxindole (XI). Subsequent condensation of oxindole (XI) with the formylpyrrole carboxamide (VIII) in the presence of piperidine in hot EtOH leads to the title compound. In an alternative procedure, oxindole (XI) is condensed with the formylpyrrole carboxylic acid (VI) giving (XII), which is further coupled with 2-(diethylamino)ethylamine (VII) in the presence of EDC/HOBt to yield the target carboxamide.
