Reactions of 5-carboxamido-5H-dibenz[bflazepines (la-ld) with glyoxylic acid methylester methyl hemiacetal (GMHA) led to 5-(carboxamido-N-a-hydroxy-acetic acid methyl ester)-5Hdibenz[b,Aazepines (2a-2d). The reactions with glycols yielded the oligoethylene glycol derivatives (3,4). The new compounds
## Abstract The synthesis of [11β^14^C]βdibenz[b,f][1,4]oxazepine 1 is described. Chromium trioxide β pyridine oxidation of 1 gives [11β^14^C]β10, 11βdihydrodibenz [b,f][1,4] oxazepinβ11βone 3 which on hydrolysis gives 2βaminoβ2β²β[^14^C]βcarboxydiphenylether 4. Hydrogenation of 1 affords [11β^14^C]
