Procedure

6.1 g of N,N′-(disulphanediyldiethane-2,1-diyl)bis(2-chloroacetamide) and 4.5 g of 4-picoline are dissolved in 50 ml of NMP and the solution is heated at 80° C. for 19 hours. After the mixture has been cooled, 9.2 g of salts are recovered by successive precipitations from acetone and drying under vacuum. The analyses show that the product conforms. 1H NMR (400 MHz, D2O): 2.61 (s, 6H), 2.82 (t, 4H), 3.56 (t, 4H), 5.31 (s, 4H), 7.85 (d, 4H), 8.51 (d, 4H).
