Compounds of the formula (IV):
or acid addition salts thereof, wherein one of the groups R5 is a group O(CH2)nYR7 wherein Y is an oxygen or sulphur atom or a methylene, OCH2 or SCH2 group, n is an integer from 1 to 5 and R7 is an optionally substituted phenyl group; the other group R5 and R6 being the same or different, each being hydrogen, halogen, C2-4alkenyl, C2-4alkenyloxy, nitro, cyano, hydroxy, benzyloxy, C1-4alkyl or C1-4alkoxy, the alkyl or alkoxy group being substituted by halogen, hydroxy, or C1-2alkoxy; amino optionally substituted by one or two C1-4 alkyl or C1-4acyl groups or the nitrogen atom forming part of a five or six membered heterocyclic ring, a group -OSO2R8 or S(O)rR8 wherein R8 is C1-3alkyl and r is 0,1 or 2 a group -COR9 wherein R9 is methyl, ethyl, methoxy, ethoxy, amino, methylamino, ethylamino, dimethylamino or diethylamino, are useful for the treatment of bacterial infections. A process for preparing these compounds and novel chemical intermediates used in their preparation are disclosed as is the first medical use of the compounds of the formula (IV) and pharmaceutical compositions containing them.
