Abstract
A manufacturing method is described for the preparation of optically active 1-(6-methoxy-2-naphthyl)-2-(alkoxycarbonyl)amino-1-propanone, its derivatives and their halo analogs. The optically active 1-(6-methoxy-2-naphthyl)-2-(alkoxycarbonyl)amino-1-propanone, its derivatives and their halo analogs are useful intermediates in the preparation of 2-(6-methoxy-2-naphthyl)propionic acid, which is useful as pharmaceutical, e.g. antiinflammatory, analgesic and anti-pyretic agents.
