Procedure
Dissolve 1,9-diazanonane (13g, 0.1 mol) in pyridine (50 mL) and cool to ° C. Add, in portions, p-toluenesulfonyl chloride (41.9 g, 0.22 mol) and stir overnight. Extract into chloroform, wash with water, 5% hydrochloric acid, water and dry (MgSO4). Evaporate the solvent in vacuo and purify by silica gel chromatography to give 1,9-bis[(4-methylphenyl)sulfonyl]-1,9-diazanonane.
