[11C]ALX-5407, R-N[3-(4′-fluorophenyl)-3-(4′-phenylphenoxy)propyl] sarcosine, a chiral glycine transporter 1 antagonist, was labeled with [11C]iodomethane by N-alkylation of methyl ester protected N-normethyl precursor, ALX-5536, and subsequent saponification of the methyl ester protecting group. The time for synthesis, purification, and formulation was 33 minutes with an average specific radioactivity of 3909 mCi/μmol (EOS) and average decay corrected radiochemical yield of 8%.
