Procedure

To 1.34 g of imidazole in suspension in heptane is added 1 ml of 2M butyllithium in hexane and the mixture is stirred at room temperature for 24 hours. To this suspension, are added 3.2 g of sulfur trioxide in dichloromethane. The slurry is stirred further for 24 hours and the solids are separated by centrifugation to yield lithium [1,3 disulfonatoimidazolium].

Workup
