Procedure

A solution of 4-nitrobenzenesulfonyl chloride (Fluka, 1.00 g; 4.51 mmol) in DCM (30 mL) was treated with 2-methoxyethylamine (Fluka, 1.9 ml; 22.6 mmol). After 2 hours, the organic solvents were evaporated in vacuo, the residue was taken up in EtOAc and extracted with a saturated NH4Cl solution. The combined organic layers were dried over MgSO4 and evaporated to dryness to give the title compound as a pale yellow solid (1.077 g, 92%).
