work contributes to its elucidation by presenting results from detailed NMR spectroscopic studies with different methods. Besides1H NMRand13C NMR,15N NMR spectroscopy is also applied.15N‐enriched urea was used for the investigations. A detailed NMR signal assignment and a model of the reaction network of the hydroxymethylation step of the synthesis are presented. Because of its higher spectral dispersion
