Production method
Use styrene to oxidize with potassium permanganate to generate acetophenone acid, and then esterify with methanol with the participation of sulfuric acid to obtain acetophenone acid methyl ester, and the latter is added with cyclopentadiene (Grignard reaction, First use metal magnesium, anhydrous ether, bromoethane to make Grignard reagent) to obtain α-cyclopentadienyl mandelate methyl ester, which is then pressurized under the action of active nickel Catalytic hydrogenation, finally, it was exchanged with N-methylpyrrolidin-3-ol ester to obtain the product.
