In a closely related method, N5-(benzyloxycarbonyl)-N2-Boc-(R)-ornithine (I) is coupled to diazomethane, via activation with isobutyl chloroformate, to afford the diazo ketone (II). Rearrangement of (II) in the presence of silver benzoate gives the beta-lysine derivative (III). After saponification of the methyl ester (III), the resultant carboxylic acid (IV) is coupled to benzyl 1-methylhydrazinoacetate (V) yielding hydrazide (VI). Hydrogenolysis of the N-carbobenzoxy groups of (VI) provides the Boc-protected precursor (VII), which is finally deprotected to the title compound under acidic conditions.
