The intermediate silyl sulfide (II) was prepared by palladium-catalyzed displacement of 5-bromo-1-methylindole (I) with potassium (triisopropylsilyl)sulfide. Alternatively, 5-iodoindole (III) was N-methylated with iodomethane and NaH, yielding 5-iodo-1-methylindole (IV), which was then reacted with potassium (triisopropylsilyl)sulfide to give (II). Condensation of silyl sulfide (II) with the aryl triflate (V) in the presence of CsF as the desilylating reagent furnished the diaryl sulfide (VI). Knoevenagel condensation of aldehyde (VI) with malonic acid (VII) gave rise to the cinnamic acid derivative (VIII). This was then coupled with ethyl isonipecotate (IX), producing amide (X). The ethyl ester of (X) was finally hydrolyzed with NaOH to yield the title sodium carboxylate salt.

In a related method, electrophilic bromination of 2,3-dichlorophenol (XI) gave (XII). Heck reaction of bromide (XII) with methyl acrylate (XIII) produced the cinnamic acid derivative (XIV). Sulfonylation of the phenolic hydroxyl of (XIV) with trifluoromethanesulfonic anhydride in pyridine furnished the aryl triflate (XV). This was coupled with the silyl sulfide intermediate (II) in the presence of CsF to produce the diaryl sulfide (XVI). After methyl ester (XVI) hydrolysis, the resultant cinnamic acid (VIII) was coupled with methyl isonipecotate (XVII) to furnish amide (XVIII). The title compound was then obtained by methyl ester (XVIII) hydrolysis with LiOH, followed by treatment with methanolic NaOH.
