[carbonyl-11C]Benzylformamide was obtained with a RCY of 80% (non-isolated, estimated by radio-HPLC) in less than 17 minutes from EOB. The application of this method to primary amines showed a linear relationship between nucleophilicity of the substrate and reactivity. The biologically-active [carbonyl-11C]formylmethionine was successfully synthesized, as well.
