Abstract
A process for preparing 2,3-dihydro-1H-1,4-benzodiazepine derivatives, and salts thereof, represented by the formula **(See formula)** wherein it means a hydrogen atom, a lower alcoholic group having up to 4 carbon atoms, or a cycloalkylmethyl group having from 4 to 7 carbon atoms; R2 means a hydrogen atom, a halogen atom, a nitro group, a lower alkoxy group having up to 4 carbon atoms, or a trifluoromethyl group; and R3 signifies a hydrogen atom, a halogen atom, a lower alcohol group having up to 4 carbon atoms, a lower alkoxy group having up to 4 carbon atoms or a trifluoromethyl group, the process of which comprises treating a diphenylmethylenimine derivative, represented by the formula **(See formula)** wherein R2 and R3 have the above meanings and X means a halogen atom, with an ethylenediamine derivative, represented by the formula R1 - NH-CH2-CH2 - NH2 (III) where it has the above meaning.
