Demoxepam[1] is a drug which is a benzodiazepine derivative. It is a metabolite of chlordiazepoxide and has anticonvulsant properties[2][3] and presumably other characteristic benzodiazepine properties.

Synthesis

Demoxepam is also an intermediate in the synthesis of oxazepam; it is also used in one of the syntheses of medazepam. It can be considered directly analogous/synonoymous with the synthesis of chlordiazepoxide, with the exception that instead of methylamine, hydroxide ion is the choice of base; here acid is not used for the cyclodehydration step though.

Demoxepam synthesis: Reeder Earl, Sternbach Leo Henryk, U.S. Patent 3,136,815 (1959 to Hoffmann La Roche).
