The reaction of o-cyclopropylphenol (I) with chloroacetonitrile (II) by means of K2CO3 in methyl ethyl ketone gives 2-(o-cyclopropylphenoxy)acetonitrile (III), which by partial hydrolysis with ethanol and dry HCl in CHCl3 is converted into the ethyl iminoether of 2-(o-cyclopropylphenoxy)acetic acid (IV). Finally, this compound is cyclized with ethylenediamine (A) in refluxing ethanol. It can also be prepared by reaction of 2-cyclopropylphenol (I) with 2-chloromethylimidazoline (V) by means of sodium ethoxide in refluxing ethanol.
