Abstract

Preparation procedure for benzodiazepine derivatives of formula: **(See formula)** wherein R1 represents Hydrogen or a hydroxy, lower alcohol, lower alkoxy, lower alkoxy-carbonyl or acyloxy group; and which may be identical or different, each represents a hydrogen or halogen atom, or a lower alcohol, lower alkoxy, trifluoromethyl, nitro, amino, mono- or di-lower alcohol-amino, lower alkanoyl-thio group, lower alcohol sulphonyl, lower alcohol-sulfinyl, carboxy, lower acyloxy-carbonyl, lower acyloxy, cyano or carbamyl; R4- represents a phenyl radical optionally substituted by at least one halogen atom or a lower alcohol group, a cyclohexane radical optionally substituted by at least one alcohol group, or a cyclohexene radical and R5 is a hydrogen or halogen atom; its N-oxides and its addition salts with acids, characterized in that ethyl glycocholate is reacted with a compound of the formula: **(See formula)** thus obtaining a compound of the formula: **(See formula)** which is cyclized by the action of heat, which provides a derivative of formula (I) in which R5 is hydrogen and, if desired, the latter derivative is reacted with a halogenating agent to obtain the derivative of formula (I) where R5 is a halogen.
