Versuchsvorschrift

To a solution of dicyclopropylmethanimine hydrobromide (0.200 g, 1.05 mmol) in 2.0 ml of dimethyl sulfoxide was added 0.232 g (2.10 mmol) of ammonium tetrafluroborate. The mixture was heated with stirring at 100° C. for 2 hours. The solvent was distilled out in vacuo and isobutyl alcohol was added to the residue. Precipitated crystals was obtained and recrystallized from ethanol to afford 0.17 g (Yield: 82%) of the desired compound.
