Procedure
To a solution of morpholine (1.91 g, 22 mmol and triethylamine (2.2 g, 22 mmol) in dichloromethane (100 mL) at 0° C. was added 2-nitrobenzenesulfonyl chloride (4.42 g, 20 mmol). The mixture was stirred for 4 h and then additional dichloromethane (100 mL) was added. The dichloromethane solution was washed with saturated NaHCO3 (2×50 mL), 10% HCl (2×50 mL) and brine (50 mL) and dried over Na2SO4. Evaporating the solvent in vacuo gave the title compound as a yellow solid (5.3 g, 97%). 1H-NMR (300 MHz, CDCl3) δ7.97 (d, J=7.3 Hz, 1H), 7.62-7.77 (m, 3H), 3.75 (t, J=4.7 Hz, 4H), 3.30 (t, J=4.8 Hz, 4H).
