참여 물질

반응 단계

To a 35 ml round-bottomed flask equipped with condenser and N2 inlet were added 0.81 g (2.55 mmol) of 4-(4-(2-chloroethyl)phenyl)-2-aminothiazole hydrobromide, 0.68 g (2.55 mmol) of N-(3-trifluoromethylphenyl)piperazine hydrochloride, 1.06 ml (7.64 mmol) of triethylamine, 0.27 g (2.55 mmol) of sodium carbonate, 2 mg of sodium iodide, and 10 ml of ethanol. The reaction was heated at reflux for 8 days, cooled, and the precipitate filtered, and the reaction mixture taken up in ethyl acetate/water. The layers were separated, the ethyl acetate washed with brine, dried, and evaporated to give a white solid, which was triturated with ethyl acetate. The solid was taken up in ethyl acetate/methanol, ether saturated with HCl added, the precipitate filtered, washed with ether, and dried to give a white solid, 0.255 g (18%), m.p. 274°-277° C.
