Abstract

A semimicro synthesis was devised to prepare pure 1,2,6,7‐^14^C‐chelidonic acid of high specific activity from 1,2‐^14^C‐oxalic acid.

## Abstract A convenient method of synthesis of 2, 6‐diaminopinelic / 1, 7 ^14^C / acid / DAP / has been elaborated. Glutaric aldehyde and K^14^CN produced the dicyanhydrine which was converted without izolation into the dihydantoine derivative of DAP by treatment with NH~4~HCO~3~. Hydrolisis /H~2~
