Dimethylformamide diethylacetal → HCID 86742772, compound

Participants

Reaction Steps

2.05 g of 1,3-bis[[p-(dimethylamino)benzylidene]amino]-2-methylimidazolium chloride and 7.35 g of N,N-dimethylformamide diethyl acetal are stirred at 100° for 45 minutes in 150 ml of 1-propanol. The product is precipitated by the addition of ether. The precipitate is crystallized from dichloromethane/methanol and recrystallized from ethanol. There is obtained 1,3-bis[[p-(dimethylamino)benzylidene]amino]-2-[2-(dimethylamino)vinyl]imidazolium chloride of melting point 246°-248°.
