Abstract
Process for the production of a compound of the formula ##STR1## in which R stands for a benzyl radical or the radical ##STR2## and X is hydrogen or represents one or more substituents, wherein a compound of the formula ##STR3## is condensed with a compound of the formula ##STR4## in which R and X have the meaning indicated, at temperatures of at least 100.degree. C on an inert solvent as reaction medium, with formation of free HCl. The products are useful as intermediates for production of the corresponding indole derivatives wherein R is replaced by hydrogen or --CH.sub.2 COOH, which are antiphlogistically active compounds.
