✦ Synopsis
In order to study "in vivo" the distribution kinetics of (-)-nicotine in animals, this molecule was labeled with carbon-11. Two synthesis methods are described. Immediately after intravenous administration of (-)-nicotine-methyl-11C in rabbits the gamma-camera shows a strong radioactivity build-up in the brain and kidneys. The biological interest of this carbon-11 labeled molecule is discussed.

Starting with "CO , [carboxyl-llC1-nicotinic acid amide was synthesized via 3-p$ridyl-lithium in practically carrierfree amounts within 60 minutes. Overall radiochemical yields between 20% and 30% were obtained. Identification and purification of the labelled product was carried out by high pressure
C-Morphine was prepared by methylation of normorphine with CH31. Acetylation of this compound yields heroin. The radiochemical yield is 9% for morphine and 4 % for heroin at a specific activity of 1.63 mCi/pmole. Synthesis time including purification by hplc is 18 min for "C-morphine and 36 min for
