반응 단계
10 g of α-[4-(4-trifluoromethylphenoxy)phenoxy]propionic acid was reacted with 80 g of methanol in the presence of 5 g of boron trifluoride at 55° to 60° C. for 3 hours. The reaction product was poured into water, and extracted with chloroform. The extract was washed with dilute alkali (i.e., 2-3% NaOH aqueous solution) and water, and dried. Then, the chloroform was evaporated off. The residue was distilled at reduced pressure to afford 7.5 g of the final product having a boiling point of 165° to 167° C./3 mmHg. The yield was 74%.
