According to the method of Tenor (J. Am. Chem. Soc., p. 159-168, 1961), 2-cyanoethylphosphoric acid pyridinium salt was prepared. Namely, 1.61 g of barium 2-cyanoethylphosphate and 10 g of an ion exchange resin (Dowex 50 (hydrogen ion form)) were suspended in water, stirred at room temperature for 30 minutes, 2 ml of pyridine was added to the supernatant, the mixture was washed with water, and the mixture then concentrated to dryness under a reduced pressure, followed by an addition of pyridine to give 1 mmol/ml of 2-cyanoethylphosphoric acid pyridinium solution.
