Versuchsvorschrift

A mixture of 2-chloro-5-nitropyridine (3.17 g, 20 mmol), morpholine (2.00 g, 23 mmol) and Et3N (2.43 g, 24 mmol) in EtOAc (200 mL) was refluxed for 3 h, then cooled to rt, and washed with water (100 mL×3). The organic phase was dried over anhydrous Na2SO4 and concentrated in vacuo to give the title compound as a yellow solid (3.89 g, 93%).
