Procedimiento

Reaction of indole XXI with acrylic acid in the presence of acetic acid affords the indole-3-propionic acid. Esterification, alkylation of the indole nitrogen, if desired, and trifluoroacetic acid hydrolysis gives rise to indoles of Formula VII in which R is (CH2)mCO2R9, m is 2 and R2 is H or C1 -C3 alkyl. ##STR29##
