title: Synthesis and biodistribution of no-carrier-added [1-11C]putrescine.
abstract: No-carrier-added [1-11C]putrescine was synthesized in 20% radiochemical yield in a synthesis time of 50 min by the Michael addition of potassium [11C]cyanide to acrylonitrile followed by reduction of the [11C]dinitrile with borane-methyl sulfide complex. Biodistribution in mice at 5, 30, and 60 min showed low uptake in normal brain tissue.
