반응 단계

33.5 g (0.3 mol) of potassium tert-butylate are initially introduced into 100 ml of anhydrous DMF at 0° C., and 51.6 g (0.25 mol) of tert-butyl 4methylphenyl-acetate in 250 ml of anhydrous DMF are added dropwise. The mixture is stirred at 0° C. for 30 minutes, 32.2 ml (0.3 mol) of cyclopentyl bromide in 150 ml of anhydrous DMF are added dropwise at 5-15° C. and the mixture is stirred at 25° C. for 20 hours. After concentration, the residue is partitioned between water and diethyl ether and the ether phase is dried over sodium sulphate and concentrated. The product crystallizes out.
