To a solution of 50 g of 4-iodobenzenesulphonyl chloride (0.165 mol) in 500 ml of CH2Cl2 there are added 46 ml of triethylamine (0.33 mol) and then, dropwise, 17 ml of morpholine (0.198 mol). Because the reaction is exothermic, the flask is placed in an ice bath until it has returned to ambient temperature. The reaction mixture is stirred for 1 hour at ambient temperature. After washing the reaction mixture with about 100 ml of 1N HCl and then 100 ml of water, the organic phase is dried (MgSO4) and evaporated under reduced pressure. The solid residue thereby obtained is re-suspended in a small amount of isopropyl ether to yield the title product after filtration and drying in vacuo.
