Alkylation of 7-hydroxyindole (I) with methyl chloroacetate (II) provided indolyl ether (III). Conjugate addition of 2-nitropropene (IV) to indole (III) in refluxing benzene, afforded the 3-(2-nitropropyl)indole (V), which was further reduced to the corresponding amine (VI) by catalytic hydrogenation over Raney nickel. Ring opening of the chiral epoxide (VII) with the racemic amine (VI) gave rise to a diastereomeric mixture of amino alcohols (VIII). After isolation of the desired (R,R)-isomer by column chromatography, basic hydrolysis of the methyl ester function yielded the title carboxylic acid.
