• (d2) opens possibilities to quantitative measurements of ApppI in biological samples by mass spectrometry. The synthesized target compound ApppI(d2) was purified by high-performance counter current chromatography and characterized by 1H, 13C, and 31P NMR spectroscopy as well as high-resolution mass

• . However, according to the literature, this is the first example reported. The procedure followed for the final synthetic step to ApppI(d2) and the detailed purification method by high-performance counter current chromatography (HPCCC) have previously been described elsewhere [21].
