Description:
<jats:p>A new reaction pathway for the synthesis of a [<jats:sup>2</jats:sup>H]‐labelled trichloroacetimidate precursor for the preparation of glucuronides is described. Therewith, stable isotope‐labelled drug glucuronides become accessible on a preparative scale, which can further be used as internal standards for quantitative analysis.</jats:p>
