A process for synthesizing a long-chain saturated α,ω-amino ester (acid) including from 6 to 17 carbon atoms, said process including a first step of cross metathesis between a first acrylic compound chosen from acrylonitrile, acrylic acid or an acrylic ester and a second monounsaturated compound including at least one nitrile, acid or ester trivalent function, one of these compounds including a nitrile function and the other an acid or ester function, in the presence of a ruthenium carbene metathesis catalyst, and a second step of hydrogenation of the monounsaturated nitrile-ester (acid) obtained, wherein said monounsaturated compound including at least one nitrile, acid or ester trivalent function has previously been subjected to a purification by thermal and/or chemical treatment.
