Procedure

To a stirred solution of morpholine (5.2 mL, 59.7 mmol) and triethylamine (11.2 mL, 79.6 mmol) in dichloromethane (300 mL) was added the solution of 4-nitro-benzenesulfonyl chloride (8.8 g, 39.8 mmol) in dichloromethane (50 mL) at 0° C. The mixture solution was stirred at room temperature for 4 h and then washed with brine (50 mL×2) and dried over anhydrous sodium sulfate. The solvent was removed in vacuo to afford 4-(4-nitro-benzenesulfonyl)-morpholine (10.0 g, 92.5%) as a white powder: MS (ESI) M+1=273.0.
