The invention provides a compound 1-methyl-cyclopentanol-acrylate. The compound 1-methyl-cyclopentanol-acrylate is characterized by being shown in a structural formula in the specification. The preparation method comprises the following steps: reacting a grignard reagent with cyclopentanone to generate 1-methyl cyclopentanol, and then reacting with acryloyl chloride, so as to generate 1-methyl-cyclopentanol-acrylate. Through providing a compound and a synthetic route thereof, and optimizing and screening the synthesis method, the problems of low productive rate, complicated reaction, high purification difficulty and the like are overcome; and the product which is high in productive rate, simple in processing process and high in purity is obtained.
