Reaktionsschritte

N-nonyl maleimide (0.02 mM) prepared as described in Example 12 above in 2 ml of acetonitrile was treated with one equivalent of triethylamine and one equivalent of N,N-dibutylethylenediamine. The reaction mixture was stirred for six hours and then the acetonitrile was evaporated. The residue obtained was treated with cold aqueous dilute hydrochloric acid solution and ethyl acetate, with stirring for one hour. The ethyl acetate layer was then separated and concentrated to give the desired product.
