Reaction Steps

To a stirred yellow solution of the 2,4-dichloro-1-((E)-2-nitro-propenyl)-benzene (1.0 mmol, 0.232 g), in methanol (3 ml) under N2 was added at 0° C. O-methylhydroxylamine hydrochloride (2.0 mmol, 0.167 g) and triethylamine (3.0 mmol, 0.30 g). After stirring for 0.5 h at 50° C., the colourless liquid cooled to ambient temperature and water (20 ml) was added. The aqueous solution was extracted with dichloromethane (20 ml), the organic layers were combined, dried (MgSO4), filtered, and evaporated under reduced pressure to afford 0.23 g (82.4% of theory) of N-[1-(2,4-dichloro-phenyl)-2-nitro-propyl]-O-methyl-hydroxylamine in the form of liquid, as a mixture of diastereomeres.
