合成路线1
Sulfenylation of the Grignard reagent derived from ethyl 5-chloroindole-2-carboxylate (I) with S-phenyl benzenethiosulfonate affords the 3-phenylsulfanyl indole (II). This is then alkylated with 4-chlorobenzyl chloride (III) in the presence of potassium hexamethyldisilazide to yield the N-benzyl indole derivative (IV). Finally, hydrolysis of ethyl ester (IV) by means of potassium trimethylsilanolate under anhydrous conditions produces the target carboxylic acid (1,2).
