Abstract This invention relates to compounds of the formula WHEREIN R1 is hydrogen or an alkyl group having 1-4 carbon atoms; R2 but R3 are hydrogen and if both R4 and R5 are hydrogen, R2 and R3 are alkyl groups having 1-4 carbon atoms or hydroxymethyl groups; R4 and R5 are hydrogen but where both R2 and R3 are hydrogen, R4 but R5 stand for alkyl groups having 1-4 carbon atoms, are amino groups, which may be mono or di-substituted by alkyl groups having 1-4 carbon atoms, or are allyloxymethyl groups; X is an oxygen or sulphur atom or an NH group; Y stands for a halogen atom or a halogeno-substituted phenyl group. The disclosure also concerns a process for the preparation of such compounds.
