実験手順
1.0 g of 1,3-bis[[p-(dimethylamino)benzylidene]amino]-2-[2-(dimethylamino)vinyl]imidazolium hydrogen carbonate is dissolved in 20 ml of methanol and 3 ml of glacial acetic acid. After 20 minutes, the solution is concentrated at room temperature in a vacuum. The product is crystallized by the addition of ether and recrystallized three times from methanol/ether. There is obtained 1,3-bis[[p-(dimethylamino)benzylidene]amino]-2-[2-dimethylamino)vinyl]imidazolium acetate of melting point 182° (dec.).
