Reaction Steps

The 5-(imidazol-1-yl)-4-methyl-3-oxa-pentanoic acid-hydrochloride used as the starting material was prepared in the following manner: reaction of the sodium salt of the imidazole with propene oxide yields the 2-(imidazol-1-yl)-1-propanol (b.p.0.1 : 147°-150° C.) from which the 5-(imidazol-1-yl)-4-methyl-3-oxa-pentanoic acid-ethyl ester (oil) is obtained by reaction with ethyl bromoacetate in dimethyl formamide in the presence of sodium hydride which is then saponified with 3N hydrochloric acid to form the desired acid.
