This invention relates to cyclobutane derivatives having the formula ##SPC1## Wherein R.sub.1 to R.sub.3, which may be the same or different, represent hydrogen atoms, halogen atoms, hydroxy, trifluoromethyl, benzyloxy, acyloxy groups, alkyl groups with 1 to 6 carbon atoms, alkoxy groups with 1 to 3 carbon atoms, phenyl, cyclohexyl, or 2 of the radicals R.sub.1 to R.sub.3 together represents a methylenedioxy group, R.sub.4 represents a hydrogen atom or an alkyl group with 1 or 2 carbon atoms, R.sub.5 represents a hydrogen atom or an alkyl group with 1 to 3 carbon atoms and R.sub.6 represents a phenyl group, which may be mono- or disubstituted by halogen atoms, trifluoromethyl, hydroxy, nitro, amino, benzyloxy, acyloxy groups, alkyl groups with 1 to 3 carbon atoms, alkoxy groups with 1 to 3 carbon atoms or alkylthio groups with 1 to 3 carbon atoms; or a pyridyl group, optionally substituted by a halogen atom, a hydroxy, nitro, amino, benzyloxy, acyloxy, carboxy group, a carbalkoxy group with 1 to 3 carbon atoms in the alkoxy, an alkyl group with 1 to 3 carbon atoms or an alkoxy group with 1 to 3 carbon atoms; To salts thereof with physiologically compatible inorganic or organic acids or bases as well as to processes for their preparation. The cyclobutane compounds of the above general formula show valuable pharmacological properties, especially a sedative and muscle relaxing activity.
