Reaction Steps

N-(3-Allyloxy-2-hydroxy-propyl)-2-methyl acrylamide made according to Example 9 (18 g, 0.09 mol), platinic chloride (4 mg, 100 ppm), BHT (36 mg, 2000 ppm) and toluene (90 mL) were charged into a 500 mL three-neck flask, equipped with a condenser with a nitrogen inlet and outlet, and a thermocouple connected to a temperature controller. Tris(trimethylsiloxy)silane (26.8 g, 0.09 mol) was added dropwise to the above mixture at 96-97° C. After stirred at about 96° C. for 16 hours, additional platonic chloride (4 mg, 100 ppm) was added to the reaction solution. The reaction was monitored by gas chromatography. After stirred for 47 hours, the reaction solution was washed with 0.5 N aqueous sodium hydroxide solution and twice with 2.5% aqueous sodium chloride solution. This was followed by washing with saturated aqueous sodium chloride solution. The organic phase was dried over sodium sulfate and filtered. The filtrate, inhibited with 4-methoxyphenol (0.02 g), was concentrated under reduced pressure at 30° C.-40° C. to give an oil (˜36 g). N-(2-hydroxy-3-(3-(tris(trimethylsilyloxy)silyl)propyloxy)propyl)-2-methyl acrylamide was purified by column chromatography.
