## Abstract The synthesis of [11‐^14^C]‐dibenz[b,f][1,4]oxazepine 1 is described. Chromium trioxide – pyridine oxidation of 1 gives [11‐^14^C]‐10, 11‐dihydrodibenz [b,f][1,4] oxazepin‐11‐one 3 which on hydrolysis gives 2‐amino‐2′‐[^14^C]‐carboxydiphenylether 4. Hydrogenation of 1 affords [11‐^14^C]
