Procedure

30 g (0.1 mol) of 4-methylphenacylpyridinium bromide in 120 ml of water were initially taken and heated to 60° C. 11 g (0.1 mol) of sodium tetrafluoroborate were then added and the mixture was slowly cooled to room temperature. It was stirred for a further hour at room temperature, and the precipitated product was filtered off and washed with water. After drying, 22.2 g (corresponding to a yield of 74%) of the title compound were obtained in the form of a yellow solid. The purity of the product was more than 99%.
