반응 단계
A mixture of 66.1 g (0.234 mol) of 2-Hydroxy-4-octyloxy benzoic acid methyl ester obtained in Step 1, 44.7 g (0.30 mol) of 5-Bromopent-1-ene, 207 g (1.5 mol) of K2CO3 and 700 mL of dry butanone is refluxed for 24 h, then allowed to return to room temperature. The reaction mixture is filtered and the butanone is distilled off under reduced pressure. After drying the residue under vacuum a slightly yellow oil (77.5 g, 95%) is obtained, which can be used in the next step without further purification.
