<p>The invention concerns a method for preparing α-aspartyl-β-cyclohexylalaninamide, characterised in that it consists in carrying out a first step of amide formation of an α-aspartyl phenylamine ester of general formula (II) wherein: R is a C1-C4 alkyl radical, then in performing a catalytic hydrogenation of the resulting α-aspartyl phenylalaninamide ammonium salt optionally released previously from its salt, and optionally transforming into an addition salt with an acid.</p> |
