NTIS ORDER NO.: DE88756677/INW ABSTRACT: Tritiated methyl iodide of high specific activity is synthetized by Fischer-Tropsch reaction of tritium with carbon monoxide, tritiated methanol obtained is reacted with hydriodic acid. It is used for the synthesis of S-adenosyl L-methionine /sup 3/H-methyl and of diazepam /sup 3/H-methyl derivatives. Synthesis of 3-PPP/sup 3/H: (hydroxy-3 phenyl)-3N-n propyl (/sup 3/H-2.3) piperidine (/sup 3/H-2.3) with a specific activity of 4.25 T Bq/mM (115 Ci/mM) and of baclofene /sup 3/H with a specific activity of 0.925 TBq (25 Ci/mM) are also described.
