Reaction Steps

In 200 ml of ethyl ether was dissolved 32.6 g of the N-methyl-3-[tris(trimethylsiloxy)silyl]propylamine obtained above, and the solution was added with 11 g of pyridine. The mixture was cooled in ice bath to 0°-5° C. Separately, 14.5 g of methacryloyl chloride was dissolved in 45 ml of ethyl ether. The methacryloyl chloride solution was placed in a separating funnel and dropped therefrom to the above mixture over about one hour. The mixture was continuously stirred for 16 hours. After the stirring, 200 ml of water was added to the reaction mixture, and the resulting mixture was stirred and then supernatant was separated. The supernatant was combined with the extract from the bottom layer with ethyl ether, and then ethyl ether was removed by heating. The residue was distilled in vacuo to give 33.0 g of a distillate at 155° C./3 mmHg.
