Comments
Synthesis: Probably due to the condition of the used triacetoxy borohydride, a better outcome of the reaction was found when using two equivalents of the borohydride. The major by-product was the acetylated amine.
Work-up: The solvent was removed from the filtered reaction mixture and the residue was subjected to chromatography on silica, using ethylacetate with a gradient of methanol as eluent.
Characterisation: The 1H NMR spectrum showed that the product was present in the form of the acetate.
