Procedure

To a stirred solution of p-toluenesulfonyl chloride (285 g, 1.50 mole) in pyridine (650 ml) at 5° C. was added a solution of 1,4,7,10-tetraazadecane (48.0 g, 0.328 mole) in pyridine (200 ml) under a dry argon atmosphere maintaining the temperature <20° C. The mixture was stirred for 3 days at room temperature. H2O (11) was slowly added to the cooled (ice bath) mixture. The solid was filtered, washed thoroughly with H2O and dried in vacuo to give 225 g (90% yield) of the product as a powder: mp 222°-4° C.; 1H NMR (DMSO-d6) δ2.38 (s,6 H), 2.41 (s, 6 H), 2.84 (quart, J=6.6 Hz, 4 H), 3.07 (t, J=7.0 Hz, 4 H), 3.12 (s, 4 H), 7.40 (m, 8 H), 7.66 (m, 8 H).
