Reaction Steps
In a 100 ml Schlenk flask, 32.16 g (0.255 moles) of dimethyl sulfate was slowly added dropwise to 20.94 g (0.255 moles) of methylimidazole with ice cooling and under a blanket gas. Stirring of the mixture was continued at room temperature over night. After the addition of 30.82 g (0.510 moles; 2 equ.) of 2-methoxyethanol, the mixture was heated at reflux at 130° C. for 48 hours. The volatile fractions were removed under high vacuum at 80° C. The product, 1,3-dimethyl-imidazolium 2-methoxyethyl sulfate, was obtained as a low-viscous, slightly yellow liquid in quantitative yield.
