The present invention relates to a method of treating hematopoietic diseases in a warm-blooded living being by administration of a composition comprising at least one compound of the general formula
wherein
R₁ is a phenyl group, a C₁-C₁₆ alkyl group, a C₆-C₁₂ (bridged) cycloalkyl group, a cyclohexadienyl group, a styryl group, a phenyl(C₁-C₄)alkyl group, an N-oxypyridyl group or a heteroaryl group having 1 or 2 nitrogen atoms in its nucleus, which groups may be substituted with one or more substituents selected from the group consisting of halogen, C₁-C₆ alkyl, C₁-C₄ haloalkyl, C₁-C₄ alkoxy, C₁-C₄ haloalkoxy, C₁-C₄ alkylthio, C₁-C₄ haloalkylthio, nitro, hydroxy, C₁-C₅ alkanoyloxy and amino, which amino group may be substituted with a C₂-C₅ alkanoyl group or with 1 or 2 C₁-C₄ alkyl groups which, together with the amino N, may form a heterocyclic ring;
X is an oxygen atom or a sulphur atom;
R₃ is a hydrogen atom, a C₁-C₄ alkyl group or a C₂-C₅ alkoxyalkyl group;
Y is an oxygen atom or a sulphur atom;
R₄ is a hydrogen atom or a C₁-C₄ alkyl group;
n is 0 or 1; and
R₂ is a hydrogen atom, a C₁-C₆ alkyl group, a phenyl group, a C₆-C₁₂ (bridged) cycloalkyl group, a phenyl(C₁-C₄)alkyl group or a heterocyclic group having 1-3 hetero atoms selected from N, O and S in its nucleus, which phenyl group, cycloalkyl group, phenylalkyl group and heterocyclic group may be substituted with one or more substituents selected from the group consisting of halogen, C₁-C₆ alkyl, C₁-C₄ haloalkyl, C₁-C₄ alkoxy, a C₁-C₄ haloalkoxy, C₁-C₄ alkylthio, C₁-C₄ haloalkylthio, C₁-C₄ alkylsulphinyl, C₁-C₄ haloalkylsulphinyl, C₁-C₄ alkylsulphonyl, C₁-C₄ haloalkylsulphonyl, optionally substituted C₃-C₁₂ cycloalkyl, optionally substituted C₃-C₁₂ cycloalkoxy, nitro, hydroxy, cyano, C₂-C₅ alkylcarbonyl, C₂-C₅ alkoxycarbonyl, optionally substituted benzoyl, optionally substituted phenoxy, optionally substituted phenyl(C₁-C₄)alkoxy, optionally substituted heteroaryloxy having 1 or 2 heteroatoms in its aromatic nucleus selected from N, O and S, and amino, which amino group may be substituted with a C₂-C₅ alkanoyl group or with 1 or 2 C₁-C₄ alkyl groups which, together with the amino N, may form a heterocyclic ring, which ring may comprise an additional N and may be substituted in its turn;
or wherein two of the said substituents together constitute a C₁-C₃ alkylenedioxy group or haloalkylenedioxy group.
