Abstract
3, 3‐Dimethylallyl pyrophosphate (DMAPP) Labeled with ^3^H on C‐1 was prepared from the corresponding acid by esterification, reduction of the methyl ester with LiAl^3^H~4~ and pyrophosphorylation of the radioactive alcohol.
The products were purified by ion‐exchange chromatography, yielding a single radioactive compound. Phosphorus analysis and gas chromatography showed that the final product was DMAPP.
