Procedure

2,2';6',2"-Terpyridine-N,N"-dioxide (7a) (0.96 g, 3.6 mmol) was suspended in dichloromethane (10 ml). N,N-dimethylcarbamyl chloride (0.95 g, 8.8 mmol) and trimethylsilyl cyanide (1.26 g, 12.7 mmol) were added. After stirring for two weeks at room temperature, 10% potassium carbonate was added until the solution was neutral. The phases were separated and the water phase was extracted with chloroform. The chloroform was evaporated and the residue was crystallized from a mixture of acetonitrile and tetrahydrofurane.
