Abstract
A process for preparing indanylamine and aminotetralin derivatives from indanone or tetralone oximes by acylating the oximes with an organic anhydride, followed by catalytic hydrogenation in the presence of an organic anhydride with subsequent hydrolysis is described. The process is commercially feasible providing indanylamine and aminotetralin derivatives in high yield that are useful as intermediates in the production of therapeutically active compounds. Also described are novel intermediates, 1-indanone O-acetyl oximes and 1-tetralone O-acetyl oximes.
