Sodium thiocyanate → HCID 86639052, compound

Participants

Reaction Steps

In 260 g of ethanol was dissolved 51.0 g of sodium thiocyanate (reagent, Wako Pure Chemical Ind. Ltd.). In 50.3 g of ethanol was dissolved 80.2 g of N-methoxymethyl-N-methylpyrrolidinium chloride. The latter solution was added dropwise to the former solution at room temperature over a period of 0.5 hour to perform salt exchange. The mixture was stirred at room temperature for 36 hours to complete the reaction and filtered. The resulting solid product was washed with 300 g of ethanol. The filtrate was dried at reduced pressure and the residue was purified through alumina column (ICN Biomedicals. GmbH, ICN Alumina N, Act.1/eluent acetonitrile). The eluate was concentrated and dried in vacuum to obtain 82.0 g of the desired product (colorless liquid). The product was checked for 1H-NMR, electrical conductivity and voltage resistance as in Example 1.
