Compounds of the general formula:- (wherein X represents a halogen atom or a trifluoromethyl group; R' represents a hydrogen atom or a.lower alkyl group and Het represents an optionally substituted C-attached 5-7 membered aromatic heterocyclic ring which ring contains one or more heteroatoms selected from 0, N and S and optionally carries a fused ring) and where a basic group is present, the salts thereof have been found to possess excellent metaphase arresting ability and are of use in combating abnormal cell proliferation. Thus a knowledge of the cell division cycles of the normal and abnormal cells enables a cytotoxic drug to be administered whilst the abnormal cells are in a phase susceptible to attack and whilst the normal cells are in a non-susceptible phase. The compounds of the invention are prepared by alkylation, deprotection of a protected keto group, oxidation or electrophilic halogenation.
