Reaction Steps

To a 35 ml round-bottomed flask equipped with condenser and N2 inlet were added 0.81 g (2.80 mmol) of 4-(4-(2-chloroethyl)phenyl)-2-amino-5-methylthiazole hydrobromide, 0.59 g (2.80 mmol) of N-(1-naphthyl)piperazine, 0.78 ml (5.60 mmol) of triethylamine, 0.30 g (2.80 mmol) of sodium carbonate, 2 mg of sodium iodide, and 10 ml of ethanol. The reaction was heated at reflux for 5 days, cooled, and the reaction taken up in ethyl acetate, washed with water and brine, dried over sodium sulfate, and evaporated to an oil. The oil was chromatographed on silica gel using ethyl acetate/methylene chloride as eluent to give a white solid. 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, 0.82 g (54%), m.p. 160°-165° C.
