Synthesis method

1. Preparation method:

In a reaction flask equipped with a Webster fractionating column, add 120.2g (1.2mol) of methyl methacrylate (2) and 74.6g (0.4mol) of lauryl alcohol ), 5.5g of hydroquinone, 2g of p-toluenesulfonic acid (or 0.5mL of concentrated sulfuric acid), and inert gas replacement 3 times. Heat to reflux under magnetic stirring for 6 to 10 hours, during which the resulting azeotrope of methanol and methyl methacrylate is continuously evaporated, with a boiling point of 55 to 65°C, until there is no distillate. The water pump decompresses and evaporates the remaining small amount of methyl methacrylate. Cool, wash with saturated sodium bicarbonate solution and water in sequence, and dry over anhydrous sodium sulfate. Add a little phenothiazine, fractionate under reduced pressure, and collect the fractions at 140-145°C/532Pa to obtain 280g of compound (1) with a yield of 92%. [1]
