✦ Synopsis


The compound 6-chloro-2,3,4,5-tetrahydroi~-methyl-l &3-t#nzazepine (SK&F 86466) was prepared in phenyl-U-C and phenyl-C , labeled forms in a six step sequence beginning with the appropriately labeled benzenes. In addition, the N-desmeJhyl analog of the carbon-1 4 labeled isotopomer and the N-methyl-H derivative of the carbon-I3 isotopomer were prepared via the N-(2,2?&trichloroethyl) carbamates by hydrolysis and lithium aluminum deuteride reduction, respectively. reylyvo r d s: ( H, C)benzazepine, ( C,)benzene, [U-Clbenzene.
