    摘要: This invention relates to new derivatives of dibenzocycloheptenes and to processes for making them. More particularly, the invention includes 5H-dibenzo[a,d]-cycloheptenes and 10,11-dihydro-5H-dibenzo[a,d]cycloheptenes which are substituted at their 5-carbon atom with an aminopropyl or an aminopropylidene radical. The amino entity may be either primary or secondary and if secondary, the substituent may be either a lower alkyl or alkenyl radical having up to 6 carbon atoms, cycloalkyl having up to 8 carbon atoms or an aralkyl radical. The dibenzocycloheptene nucleus may be further substituted. The invention also includes the intermediates used for obtaining these products. Also included are derivatives such as acyl derivatives which yield the active compound under physiological conditions.
