실험 절차

The procedure of Example 2 was followed. 3.9 g of trimethyloxonium tetrafluoroborate in suspension in 20 ml of 1,2-dichloroethane was added to 2.1 ml (2.16 g) of N-methylimidazole in 5 ml of 1,2-dichloroethane. The mixture was stirred for 4 hours at room temperature. A salt was formed (lower phase) which was non miscible with the solvent and was separated by decanting. The remaining solvent was evaporated off under vacuum using a vane pump. A colorless liquid was obtained.
