Caroxazone (Surodil, Timostenil) is an antidepressant which was formerly used for the treatment of depression but is now no longer marketed.[2][3] It acts as a reversible monoamine oxidase inhibitor (RIMA) of both MAO-A and MAO-B subtypes, with five-fold preference for the latter.[4][5][6][7][8]

Synthesis

Caroxazone synthesis:[9][10][11][12][13]

Synthesis starts by reductive amination of salicylaldehyde and glycinamide to give 3. The synthesis is completed by reaction with phosgene and NaHCO3.
