Traitement

  1. 1
    AutreHydrogen chloride and an excess of HBF4 were removed from the mixture in a vacuum

Mode opératoire

A 15.0 g quantity of the N-methyl-N-methoxymethylpyrrolidinium chloride (N-methoxymethyl-N-methylpyrrolidinium chloride) prepared in Example 1 was dissolved in 35 g of MeOH, and 27.83 g of methanol solution of 30% HBF4 was added to the solution. Hydrogen chloride and an excess of HBF4 were removed from the mixture in a vacuum to obtain 19.6 g of the desired product (pale yellow liquid).
