✦ Synopsis
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 llC-heroin, respectively. The tissue distribution of both these compounds was determined in rats at different times after an i.v. injection.

## Abstract The radiochemical synthesis of N‐[^11^C‐methyl]‐L‐DOPA was accomplished by N‐methylation of the methyl and ethyl esters of L‐N‐tert‐butyl‐oxycarbonyl‐[β‐(3,4‐dimethoxyphenyl)] alaninate with [^11^C]iodomethane using sodium hydride in tetrahydrofuran and deprotection of the N‐methyl inte
## Abstract [^11^C]Paraquat was synthesized by the reaction of [^11^C]methyl triflate with the mono‐triflate salt of 1‐methyl‐[4,4′]bipyridinyl. The product was selectively separated from the precursor by a microcolumn of Chelex 100 ion exchange resin. The method was applied to the synthesis of a v
## Abstract 3‐[^11^C]‐Methyl‐D‐glucose was synthetized by methylation via ^11^CH^3^I of the potassium salt of diacetone‐D‐glucose; hydrolysis of the ketal groups with HCl yields 3‐[^11^C]‐methyl‐D‐glucose. The radiochemical yield is 35% at a specific activity of 1.9 mCi/μmole. Synthesis time includ
