CA 2591042

Processes are disclosed for the preparation of a compound having the formula: (I) and intermediate compounds wherein M is a single-photon-emission tomography imageable radiometal and/or a paramagnetic metal, R is hydrogen or a halogen provided that at least one R is halogen and Y is selected from ortho, meta or para O(CH2)nC2HB9H10 or O(CH2)nC2HB 10H10 wherein n is 0 or an integer from 1 to 20 and O(CH2)nC2HB9H10 is nido ortho-, meta- or para- carborane and O(CH2)nC2HB10H10 is ortho-, meta- or para-carborane.

L'invention concerne des procédés de préparation d'un composé représenté par la formule (I) et de composés intermédiaires. Dans la formule, M est un radiométal et/ou un métal paramagnétique pouvant être imagé par tomographie par émission de photon unique, R représente hydrogène ou un halogène, à condition qu'au moins un R représente halogène et que Y soit sélectionné entre O(CH2)nC2HB9H10 en position ortho, méta ou para ou O(CH2)nC2HB10H10, n représentant 0 ou un nombre entier compris entre 1 et 20; O(CH2)nC2HB9H10 représentant nido ortho-, méta- ou para-carborane; et O(CH2)nC2HB10H10 représentant ortho-, méta- ou para-carborane.
