Versuchsvorschrift

{4-[(4-Chloropyrimidin-2-yl)methyl]morpholin-3-yl}methanol (200 mg, 0.821 mmol) was taken up in DCM (4 mL) and cooled to 0° C. DAST (0.119 mL, 0.903 mmol) was added and the resulting mixture stirred at 0° C. for 90 minutes. Saturated NaHCO3 was added and the products extracted into EtOAc (2×). The combined organic extracts were washed with brine, dried over MgSO4, filtered, and concentrated in vacuo. Purification of the residue by silica gel chromatography (12-100% EtOAc-hexanes) followed by HPLC (10-40% MeCN—H2O) gave the title compound as a pale yellow gum.
