Morpholine (2.2 ml, 25 mmol) was slowly added to 3-Nitro-benzenesulfonyl chloride (5.5 g, 25 mmol) in CH2Cl2 at 0° C. The reaction was warmed up to rt in 0.5 h. After CH2Cl2 was removed in vacuo, saturated NaHCO3 solution was added and the solid was filtered and dried to give 4-(3-Nitro-benzenesulfonyl)-morpholine as an off white solid (5.9 g, 87%). MS (ESI) m/z=273 [M+H]+.
