Versuchsvorschrift

4-bromobenzoyl chloride (5 g, 22.78 mmol) was taken up in THF (75 mL) and cooled to 0° C. A solution of morpholine (2.084 mL, 23.92 mmol) and DIPEA (4.38 mL, 25.06 mmol) in THF (25 mL) was added dropwise and the resulting mixture stirred at 0° C. for 3 hours. Water as added and the products extracted into EtOAc (×2). The combined organic extracts were washed with brine, dried over MgSO4 and concentrated in vacuo to give 4-(4-bromobenzoyl)morpholine as a pale yellow gum.
