Olanzapine and its precursor desmethyl-Olanzapine were synthesized from malononitrile, propionaldehyde, 1-fluoro-2-nitrobenzene, and substituted piperazine in 4, 4, 5, and 5 steps with 35%, 32%, 26%, and 32% overall chemical yield, respectively. [11C]Olanzapine was prepared from desmethyl-Olanzapine with [11C]CH3OTf through N-[ 11C]methylation and isolated by HPLC combined with solid-phase extraction (SPE) in 40-50% radiochemical yield based on [11C]CO 2 and decay corrected to end of bombardment (EOB), with 370-740 GBq/μmol specific activity at EOB. The calculated Log P (C Log P) value of [11C]Olanzapine is 3.39.
