Embodiment 1
[0048] Step 1: Stir and mix 0.192g (1.1mmol) 1,10-decanediol, 0.111g (1.1mmol) triethylamine and 20ml dichloromethane at 5°C at a speed of 600r / min to form the first mixed solution ;
[0049] Step 2: Mix 0.090g (1mmol) of acryloyl chloride and 20ml of dichloromethane into a constant pressure dropping funnel to completely dissolve them to form a second mixed solution;
[0050]Step 3: Pour the second mixed solution obtained in step 2 into the first mixed solution obtained in step 1, stir and mix, and react at a temperature of 25°C and a rotational speed of 1800r / min, and the reaction time is 20h; the reaction ends After filtering to remove the precipitate, dry at 35°C and 0.09Mpa for 10 minutes to obtain the crude product; the crude product was separated by silica gel column chromatography (petroleum ether: ethyl acetate = 1:1) to obtain the pure product A;
[0051] Step 4: Dissolve the obtained product A and 0.009g (0.05mmol) p-toluenesulfonic acid in 20mol methylene chloride,...
Embodiment 2
