Compounds of the general formula (2) ##STR1## wherein n is an integer of from 3 to 10, the iodo substituent is in the 3- or 4-position and R.sup.1 and R.sup.2, which may be the same or different, represent C.sub.1-3 alkyl, especially methyl or ethyl, groups or R.sup.l represents a hydrogen atom and R.sup.2 a C.sub.1-3 alkyl group or R.sup.1 and R.sup.2 together with the nitrogen atom to which they are attached represent a saturated heterocyclic group, especially a pyrrolidino group, in the form of their free bases or pharmaceutically acceptable acid addition salts are potent anti-oestrogenic compounds useful for treatment of oestrogen-dependent cancers, especially breast cancers. Compounds where the iodine atom is radioisotopic are useful in radiotherapy or gamma ray imaging of these cancers.
