Novel imidazole derivatives are disclosed. These compounds have a good affinity to the NMDA (N-methyl-D-aspartate)-receptor subtype selective blockers, which have a key function in modulating neuronal activity and plasticity which makes them key players in mediating processes underlying development of CNS as well as learning and memory formation. These compounds are useful in the control or treatment of diseases mediated by this receptor.

The invention provides compounds of the formula:
wherein R1, R2 and R3, which can be the same or different, are each selected from hydrogen, chloro, bromo, fluoro, methyl, ethyl, methoxy, amino, hydroxy and nitro; R4 is hydrogen or alkyl of 1 to 7 carbon atoms; -X- is
wherein R5 is hydrogen, hydroxy or-OR6, and R6 is alkyl of 1 to 7 carbon atoms or aryl of 6 to 10 carbon atoms; and their non-toxic pharmaceutically acceptable acid addition salts and mixtures thereof. Processes for the preparation and use of the subject compounds are described, as are novel pharmaceutical compositions comprising at least one of the subject compounds or their salts. The compounds and their non-toxic salts exhibit valuable pharmacological activity and are useful in the treatment of mammals, particularly as anti-hypertensive or anti-ulcer agents. Furthermore, they are useful as diuretic, sedative, analgesic, anti-inflammatory and tranquilizing agents.
