Compound can be prepared in two different ways: 1) The condensation of 2,6-dichlorophenol (I) with alpha-bromopropionitrile (II) by means of K2CO3 in refluxing butanone gives alpha-(2,6-dichlorophenoxy)propionitrile (III), which by hydrolysis with ethanol and HCl affords ethyl ester hydrochloride (IV). Finally, this compound is cyclized with ethylenediamine (A) in ethanol at 70 C. 2) By condensation of sodium 2,6-dichlorophenolate (V) with 2-(alpha-chloroethyl)-2-imidazoline (VI) in refluxing dioxane.
