✦ Synopsis
I4C-Labeled inosine 5'-phosphate was synthesized by direct phosphorylation of i n 0 s i n e -8 -~~C with phosphoryl chloride followed by hydrolysis of the resulting phosphorodichloridate. Isolation and recrystallization o f its disodium salt afforded pure material in 66.8% overall chemical yield.

A new procedure has been developed for the synthesis of I4C-labeled glutethimide with an improved yield from K14CN. In this procedure benzyl cyanide prepared from benzyl chloride and K14CN was almost quantitatively monoethylated by an ion-pair extraction method using 50% excess of tetrabutylammonium
Ring-labeled bunolol, df -5 -[3 -(tertbutylamino) -2-hydroxypropoxyJ-3,Cdihydro-l(2ti)-naphthalenone-l-~4C, was synthesized in several steps by initially allowing 3-phenylpropylmag-lJ4C acid was cyclized to a-tetralone-lJ4C. The ring was then oxidized and opened to 4-(2-hydroxyphenyl)butyri~l-~~C ac
## Abstract A versatile method for ^14^C labeling of 2‐methoxypyrimidine‐5‐carboxylic acid at the 2‐position has been developed after encountering difficulties with traditional approaches to label the carboxyl function. The method developed can also be used for ^14^C labeling other positions of the
