AbstractSpecifically, 15N‐enriched L‐histidines have been prepared. The labelling methodology involves introduction of labels in its precursor 1‐benzyl‐5‐hydroxy methyl imidazole, which is converted into L‐histidine via the Schöllkopf method. The procedure allows the preparation of the intermediates and finally histidine with high 15N enrichment (99%) at each position, in 29% overall yield starting with 15NH4Cl and 56% with KSC15N, respectively.
