Certain radioiodine containing amines useful as brain imaging agents as well as their preparation are disclosed. The compounds of the invention are represented by the formula
Wherein I is a radioisotope of iodine with 1-123 being preferred, R is lower alkyl or halogen, R and R2 are the same or different and are selected from the group consisting of hydrogen and lower alkyl, R3 and R4 are the same or different and are selected from the group consisting of hydrogen, alkyl, aryl, substituted aryl, aralkyl, substituted aralkyl and substituted carbamoylmethyl or R3 and R4 taken together with the nitrogen to which they are attached form a 5- or 6-membered ring which may be substituted with one or more lower alkyl groups, x is 0 to 4, y is 0 to 3 and z is 0 or 1, and pharmaceutically acceptable acid addition salts thereof.
