Abstract
PHA‐690509, a cyclin‐dependent kinase A inhibitor, has been labelled with carbon‐14. [^14^C]PHA‐690509 was obtained via a three‐step procedure in 10% overall radiochemical yield starting from [^14^C]thiourea 3. Copyright © 2007 John Wiley & Sons, Ltd.

14C labelled Metribuzine was synthetised in a five step synthesis firom sodium [l-14C]pivalate (trimethyl acetic acid) via o-brom0-[2-~~C]pinacoline (l-bromo-3,3-dimethyl-butan-2-on) and trimethyl [2-14C]pyruvic acid. The total yield was 30% (calculated on sodium pivalate).
## Abstract Hexazinone ‐ a s‐triazine type contact herbicide ‐ was labelled with ^14^C for the investigation of metabolic pathways. A convenient synthesis was elaborated for labelling of the carbon atom in the 6 position of the triazine ring. The molar activity of Hexazinone was 797.0 MBq/mmole (21
14C-Labelled satigrel, or 4-cyano-5-(4'-methoxy tring-U-14CI phenyl)-5-(4"methoxyphenyl)-4-pentenoic acid was synthesized for drug metabolism and pharmacokinetic studies using 4,4'-diniethoxy [ring-U-W ] benzophenone as the starting material. The radiochemical yield was 10.0%. The specific radioacti
The synthesis of 14C-labelled crotamiton, which is a fungicide, an insecticide as well as a scabicide is described. Starting from 2-bromonitrobenzene and Cu14CN, 2-toluidine, labelled with 14C at the methyl group was prepared by the following sequence of reactions : N O ~-C ~H L + -~~C O O H
## Abstract [^14^C]Aminoguanidine was synthesized by the reaction of hydrazine sulphate with barium [^14^C]cyanamide in a one‐step synthesis, and conveniently isolated by crystallization as the bicarbonate salt. The yield was 32%.
