A solution of 4.70 g (85% purity, 35.65 mmol) of trifluoroacetamidine and 10.93 g (35.65 mmol) of ((Z)-2-chloro-3-dimethylamino-allylidene)-dimethyl-ammonium; hexafluoro phosphate [Davies, Ian W.; Marcoux, Jean-Francois; Wu, Jimmy; Palucki, Michael; Corley, Edward G.; Robbins, Michael A.; Tsou, Nancy, Ball, Richard G.; Dormer, Peter; Larsen, Robert D.; Reider, Paul J, Journal of Organic Chemistry 2000, 65(15), 4571-4574] in 70 ml acetonitrile was treated with 4.33 ml (42.78 mol) of triethylamine and stirred for 4 h at room temperature. The reaction was poured into 250 ml of water and extracted with ether (three times). The organic phases were washed with water (two times), dried (Na2SO4) and carefully evaporated to give 3.66 g of the title compound as an orange volatile liquid.
