반응 단계
2,2-Dimethyl-4-pentenoic acid (15 g, 0.117 mol) was mixed with 70 mL anhydrous methanol and 50 mL toluene. Concentrated sulfuric acid (0.1 mL) was added. The solution was refluxed for 24 h. Solvents were then removed. The crude product was distilled under reduced pressure to gave 6 g pure product. 1H NMR (CDCl3): δ 1.28 (s, 6H, —CMe2-); 2.37 (d, 2H, CH2═CHCH2—); 3.77 (s, 3H, —CO2Me); 5.15 (m, 2H, CH2═CH—); 5.84 (m, 1H, CH2═CH—).
