Abstract
A method is described by which 60 mCi11C propranolol may be obtained from about 1 Ci11CO2 in 30 min without irradiation risk for personnel. The product is chromatographically pure, sterile and apyrogenic with a specific activity between 500 mCi and 2 Ci/μmole at the time of use. The synthesis involves the preparation of11C acetone followed by fixation of the isopropyl group on the precursor [1-amino-3-(1-naphtyloxy)-2-propanol] by formation of an imine, then reduction of the latter by sodium cyanoboro hydride. The influence of certain parameters (reagents, precursor, impurities) on the final product is discussed.
