Procedure

1,2-Dimethyl-1-propylpiperidinium bromide (5.3 g, 22 mmol) and lithium bis(trifluoromethanesulfonyl)imide (7.09 g, 25 mmol) were mixed and stirred in pure water, so that a room-temperature ionic liquid which is insoluble in water was obtained immediately. The obtained room-temperature ionic liquid was extracted with methylene chloride and then washed with pure water six times and dried in vacuum at 100° C.; thus, 1,2-dimethyl-1-propylpiperidinium bis(trifluoromethanesulfonyl)imide (9.37 g, 21 mmol) was obtained.
