Abstract

1-Ethyl-imidazoles of the formula ##SPC1## Or a pharmaceutically acceptable nontoxic salt thereof, are produced by PA1 A. reacting a compound of the formula ##SPC2## With imidazole; or PA1 B. when R.sup.1 is hydrogen, reacting a compound of the formula ##SPC3## With imidazole in the presence of an acid binding agent. In the case of the salts the free base produced is reacted with an appropriate acid. The 1-ethyl-imidazoles are useful for their antimycotic activity.
