Abstract

A process for preparing esters of [(1,2,4-oxadiazol-3-yl) phenyl] carbamic acid of the formula: ** (See formula) ** where X is oxygen or sulfur; R is selected from the group consisting of hydrogen, lower alcohol, phenyl, chlorine, bromine, lower alkoxy, trifluoromethyl, phenoxy, and di (lower alcohol) amino; R1 is selected from the group consisting of hydrogen, lower alcohol, 3- to 6-cycloalkoxy, or a 5- or 6-membered heterocyclic ring containing 1 to 3 heteroatoms selected from the group consisting of oxygen, sulfur, and nitrogen, phenyl, and substituted phenyl; and R3 is selected from the group consisting of lower alcohol, substituted lower alcohol, lower alkenyl, lower alkynyl; cycloalkoxy of 3 to 6 carbons, phenyl and substituted phenyl; said phenyl substituent being 1 or 2 members selected from the group consisting of fluorine, chlorine, bromine, iodine, nitro, amino, trifluoromethyl, lower alcohol and lower alkoxy or trimethoxy and said lower alcohol substituent being one or more members selected from the group consisting of chlorine, bromine, fluorine, and iodine; and its pharmaceutically acceptable salts, characterized by reacting a compound of the formula ** (See formula) ** with a compound of the formula (see formula).
