Abstract

168 H. Takalo and J. Kankare Vol. 27 ed a method in which these three steps can be made in one pot with good results. Unfortunately when this procedure was used with 2 and bis(3-aminopropyl)amine, the product without a bromogroup dominated over 3a. The product proportion was 3:1 according to the nmr spectra. The un- wanted reaction must be due to the activation ability of nickel(II) cation in the sodium borohydride reduction step because ...
