In detail, the new processes, according to the present invention, are ultimately related to the synthesis of intermediates to prepare the above NEP inhibitors, namely compounds according to formula (1), or salt thereof, n nwherein R1 and R2 are, independently of each other, hydrogen or a nitrogen protecting group, and R3 is a carboxyl group or an ester group, preferably carboxyl group or alkyl ester.
