Procedure

2.52 g (14.8 mM) of 2-iodopropane was added to an N,N-dimethylformamide solution (30 ml) of 2.00 g (15.6 mM) of 3-amino-2,3-bis(hydroxyimino)propionitrile. The mixture was cooled to 0° C. 2.05 g (14.8 mM) of potassium carbonate was added, followed by stirring at room temperature for 16 hours. The reaction mixture was poured into water, followed by extraction with ethyl acetate. The organic layer obtained was washed with a saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, and filtered to remove inorganic matter. The solvent was distilled off under reduced pressure. The resulting residue was purified by silica gel column chromatography (ethyl acetete:hexane=1:2) to obtain 1.36 g (yield: 51%) of 3-amino-3-hydroxyimino-2-isopropoxyiminopropionitrile (compound No. 1-004).
