The invention relates to a process for producing a compound according to formula (i)
wherein R1 and R1' are independently hydrogen or an amine protecting group and R2 is a carboxylic group or derivative thereof, comprising reacting a compound according to formula (ii)
wherein R1, R1' and R2 are defined as above, with hydrogen in the presence of a transition metal catalyst and optionally a chiral ligand, wherein the transition metal is selected from group 7, 8 or 9 of the periodic table. Furthermore, the invention relates to products obtainable by said process and to their use in the production of NEP inhibitors. Moreover, the invention relates to the use of transition metal catalyst in the preparation of NEP inhibitors or prodrugs thereof.
