Abstract

Starting with [14C]-D-tyrosine, carbon-14 labeled JDTic dihydrochloride with specific activity 15 mCi/mol was prepared in 5% radiochemical yield. Separation of the (3R)- and (3S)-diastereomers was carried out via the 3-phenyl-2,3,10,10a-tetrahydro-5H-imidazo[1,5-b]isoquinolin-1-ones formed by reaction with benzaldehyde.
