Reaktionsschritte

The compounds of Formula I can be prepared by conducting an Arndt-Eistert reaction upon 5-oxo-5H-dibenzo[a,d]-cycloheptene-2-carboxylic acid to afford, in various steps thereof, 5-oxo-5H-dibenzo[a,d]cyclohepten -2-acetic acid ethyl ester and 5-oxo-5H-dibenzo[a,d]cyclohepten-2-acetic acid. 2-(5-Oxo-5H-dibenzo[a,d]cyclohepten-2-yl)propionic acid, and the corresponding esters of the aforementioned acids can be obtained via alkylation and/or esterification.
