Procedure

Suspend sodium hydride (4.8 g, 0.2 mol) in anhydrous dimethylformamide (100 mL), cool to 0° C. and place under a nitrogen atmosphere. Add, by dropwise addition, a solution 1,9-bis[(4-methylphenyl)sulfonyl]-1,9-diazanonane (43.8 g, 0.1 mol) in dimethylformamide. Stir until evolution of hydrogen ceases. Add, by dropwise addition, a solution of N-(t-butyloxycarbonyl)-N-[(4-methylphenyl)sulfonyl]-4-chlorobutylamine (72.4 g, 0.2 mol) in dimethylformamide (100 mL). Stir overnight at room temperature then carefully quench with saturated ammonium chloride. Extract into ethyl acetate, dry (MgSO4) and evaporate the solvent in vacuo. Purify by silica gel chromatography to give the title compound.
