Reaction Steps

To a solution of (3-Dimethylamino-2-trifluoromethyl-allylidene)-dimethyl-ammonium chloride ([176214-18-9], 0.60 g) in acetonitrile (10 mL) was added 4-Benzyl-piperazine-1-carboxamidine hydrochloride ([7773-69-5], 0.66 g) and triethylamine (0.87 mL) and the reaction mixture was stirred for 3 hours at room temperature. After such time the reaction mixture was concentrated in vacuo and purified by column chromatography to yield the title compound as a light yellow solid (0.79 g). MS (m/e): 323.4 (M+H+).
