β¦ Synopsis
Tritium labelled 8-chloro-l-[(dimethylamino)methyl]-6-phenyl-4H-striazolo[4,3-a][ 1,4]benzodiazepine was prepared from [3Hlbromomethane and 8chloro-I -[(N-methylamino)methyl]-6-phenyl-4H-s-triazolo[4,3-a][ 1.4lbenzodiazepine. The latter compound was efficiently obtained from 8-chloro-6-phenyl- 4H-s-triazol0[4,3-a][1,4]bentodiazepine by hydroxymethylation, mesylation and mesylate displacement with aqueous methylamine. The titled product had a specific activity of 80 Ci/mmole.
