2‐14C‐oxazepam (7) 2‐14C‐(+)‐ and ‐(‐)‐7‐chloro‐1‐methyl‐5‐phenyl‐1,3,4,5‐tetrahydro‐3H‐1,4‐benzodiazepine‐2‐one (8a and 8b) as well as 2‐14‐7‐chloro‐4‐carbamoyl‐1‐methyl‐5‐phenyl‐1,3,4,5‐tetrahydro‐3H‐l,4‐benzodiazepine‐2‐one (9) were synthesised from carbobenzoxy‐glycine‐1‐14C. The overall radiochemical yields from carbobenzoxy‐glycine‐1‐14C were 28.9 % (7), 9.5 % (8a and 8b) and 25.3 % (9), respectively.
