1-Hexyl-3-methylimidazolium trifluoromethanesulfonate

1-Hexyl-3-methyltetrafluoromethanesulfonate imidazolonium is a sulfonate that can be used as a pharmaceutical synthesis intermediate.

Yellow low melting solid

A mixture of 1.80 g (8.88 mmol) of isohexyl-3-methylimidazolium chloride and 1.52 g (9.26 mmol) of methyl trifluoromethanesulfonate CF3SO2OCH 3 was stirred at room temperature for 30 min. NMR measurements showed the completeness of the reaction. The residue was dried under vacuum at 13.3 Pa and 120 C (oil bath temperature) for 30 min. 2.80 g of imidazolium 1-hexyl-3-methyltetrafluoromethanesulfonate was obtained in a quantitative amount.
