Abstract
New phenylethanolaminomethyltetralins of formula (I) ##STR1## wherein E represents hydrogen, (C.sub.1 -C.sub.4)alkyl, (C.sub.1 -C.sub.4)alkoxy, phenyl, nitro, halogen, or trifluoromethyl, PA1 L represents hydrogen, (C.sub.1 -C.sub.4)alkyl, (C.sub.1 -C.sub.4)alkyoxy, phenyl, nitro, or halogen, or PA1 E and L taken together represent a group --CH.dbd.CH--CH.dbd.CH-- or --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --, and PA1 G represents hydrogen, chloro, hydroxy or an --OG' group wherein G' represents a (C.sub.1 -C.sub.4 (alkyl group either unsubstituted or substituted with hydroxy, (C.sub.1 -C.sub.4)alkoxy, (C.sub.1 -C.sub.4)alkoxycarbonyl, carboxy, or (C.sub.3 -C.sub.7)cycloalkyl; a (C.sub.3 -C.sub.7)cycloalkyl group; or a (C.sub.2 -C.sub.4)alkanoyl group; and salts thereof, are described which showed to be active as intestinal motility modulating agents and intraocular hypertension lowering agents. Also described is a process for the preparation of the new compounds and the intermediates of formula (III) ##STR2## employed in said process.
