Procedure

In this way a milky suspension is obtained which is washed twice with 136 g of dichloromethane, then the chloromethylenic phases are reunited, dried over anhydrous magnesium sulphate and finally concentrated under vacuum. In this way 7.5 g of a yellow oil is isolated which is purified by preparative chromatography on a column (500×25) filled with silica of a size grading of 10 micrometers, eluting with a hexane-ethyl acetate mixture 8/2 by volume, which allows the isolation on the one hand of, 5 g (20.4 mmoles) of 1-methacryloyloxy-3-methoxyiminoacetoxy-2-propanol, and on the other hand of, 2 g (8.15 mmoles) of 3-methacryloyloxy-2-methoxyiminoacetoxy-1-propanol characterised by their NMR1H spectra registered in deuterized chloroform.
