An antifungal agent of the formula:-
where R is a phenyl group optionally substituted by 1 to 3 substituents each independently selected from halo and CF3; R' is either (a) a phenyl group substituted by a group of the formula -N=CH-N(C1-C4 alkyl)2,
or (b) a 5- or 6-membered aromatic heterocyclic group which is optionally benzo-fused and optionally substituted by 1 or 2 substituents each independently selected from halo, C1-C4 alkyl and halo-(C1 or C2 alkyl), said heterocyclic group being attached to the nitrogen atom of the piperazine ring by a carbon atom; and R2 is H or CH3; or an O-ester or O-ether thereof which is a C2-C4 alkanoyl or benzoyl ester, or a C1-C4 alkyl, C2-C4 alkenyl, phenyl-(C1-C4 alkyl) or phenyl ether, said phenyl and benzoyl groups of said O-esters and O-ethers being optionally substituted by one or two substituetns each selected from C1-C4 alkyl, halo and halo-(C1 or C2 alkyi); or a pharmaceutically acceptable salt thereof.
