Participants

Reaction Steps

0.023 g (0.001 g-atom) of sodium are dissolved under nitrogen in 15 ml of absolute methanol. 2.34 g (0.01 mol) of 6,6'-dicyano-4,4'-dimethyl-2,2'-bipyridine are added to that solution, and the resulting mixture is stirred at room temperature for 2 days. 1.34 g (0.025 mol) of ammonium chloride, 10 ml of absolute methanol and 20 ml of a saturated ethanolic ammonia solution are then added, and the mixture is stirred at 70° for one hour. After cooling, the reaction mixture is concentrated to dryness by evaporation and the residue is crystallised from dilute hydrochloric acid, yielding the title compound, m.p.>240°; MS(FAB): (M+H)+ =269; 1H-NMR (D2O): δ=8.39 (d,2H); 7.88 (d,2H) 2.46 (s,6H).
