Abstract
Novel compounds constituting esters of benzoic acids, selected from the group consisting of p-vinyl benzoic acid and p-ethynyl benzoic acid, with an aminoethanol selected from the group consisting of diethylaminoethanol and N-substituted aminoethanols. The esters have the formula ##STR1## where X is selected from the group consisting of ##STR2## or HC.tbd.C and each of R.sub.1 and R.sub.2 is selected from the group consisting of H, lower alkyls containing up to 6 carbon atoms and cycloalkyls. The novel compounds also include inorganic and organic acid salts of said esters. The novel compounds have a unique medicinal function as local subcutaneously-applied anesthetics which have a long-acting effect when administered without vasoconstrictors that heretofore have been used to prevent rapid dissipation of subcutaneously-applied local anesthetics. The invention also embraces compositions containing the compounds and the method of using the novel compounds and compositions as local long-acting subcutaneously-applied anesthetics.
