Reaction Steps

Ethyl 3-bromo-2-(hydroxyimino)propanoate (4.0 g, 19 mmole) and methacryloyl chloride (2.18 g, 20.8 mmole) in methylene chloride (100 ml) were treated with dry pyridine (1.66 g, 21 mmole). After a workup as in Example 1, 4.42 g (84% yield) of ethyl 3-bromo-2-(methacryloyloximino)propanoate was obtained as an oil. NMR and IR spectra confirm the structure.
