반응 단계

A four-necked flask equipped with a stirrer, a thermometer, and a dropping funnel was charged with 7.9 g (0.04 mol) of 1-ethyl-4-trifluoromethylcyclohexanol, 0.2 g of 4-dimethylaminopyridine, 4.9 g of triethylamine, and 20 g of acetone. The mixture was stirred to obtain a solution. A solution prepared by dissolving 4.6 g (0.044 mol) of methacrylic acid chloride in 5 g of acetone was added to the solution at 4° C. over 30 minutes. The mixture was stirred at 4° C. for 3 hours to obtain a reaction mixture. The reaction mixture was washed with water to obtain 8.0 g of 1-ethyl-4-(trifluoromethyl)cyclohexyl methacrylate (hereinafter may be referred to as “compound (M-3)” ((M-3) in Table 1)). The yield of 1-ethyl-4-(trifluoromethyl)cyclohexyl methacrylate with respect to 1-ethyl-4-trifluoromethylcyclohexanol was 76%.
