실험 절차

Gaseous dimethylamine is passed through a mixture of 2.47 g of 1,3-bis[[p-(dimethylamino)benzylidene]amino]-2(methylthio)imidazolium tetrafluoroborate and 30 ml of absolute dimethylformamide until a weight increase of 0.4 g (corresponding to 1.8 equivalents) is achieved and the mixture is subsequently stirred at room temperature overnight. From the resulting reddish solution, there is obtained by the addition of diethyl ether a crystalline precipitate which is removed by filtration under suction and washed twice with water and ethanol each time. After re-precipitation from dimethylformamide/diethyl ether, there is obtained 1,3-bis[[p-(dimethylamino)benzylidene]amino]-2-(dimethylamino)imidazolium tetrafluoroborate as a yellow solid of melting point 248°-252° (decomposition).
