실험 절차

To a suspension of 1.79 g (5.41 mmol) of 2-[6-(4-chlorophenoxy)-1-fluorohexyl]-2-oxiranecarboxylic acid methyl ester (isomer A) of Example 3 in 5.14 ml of absolute ethanol is added at room temperature 5.14 ml (5.14 mmol) of 1N aqueous sodium hydroxide. After 30 minutes, 4.0 ml of tetrahydrofuran is aded to achieve total dissolution and stirring is maintained for 1.25 hours. Evaporation of the solvents and trituration with pentane and isopropyl ether gives 1.46 g (79.7%) of the title compound: m.p. 112°-125° C.; IR (KBr) 1640, 1608 cm-1 ; NMR (d6 -DMSO) δ 1.47 (4H, m), 1.74 (4H, m), 2.63 (1H, dd, J=8, 3 Hz), 2.73 (1H, d, J=8 Hz), 3.98 (2H, t, J=9 Hz), 5.19 (1H, ddd, J=48, 10, 2 Hz), 6.98 (2H, d, J=8 Hz).
