It is known to very slowly decompose in the presence of water.R.P. Swatloski J.D. Holbrey R.D.

It may be obtained in two steps, as shown below. BMIM-Cl is synthesized by alkylating the compound 1-methylimidazole with 1-chlorobutane. A metathesis reaction with potassium hexafluorophosphate and the product from the previous reaction gives the desired compound. BMIM-BF4 may be prepared by analogously using potassium tetrafluoroborate in place of the hexafluorophosphate.
