实验步骤: To a solution of 0.28 g 3,5-dichloro-2-fluoro-4-(1,1,2,3,3,3-hexafluoropropoxy) aniline in 8 mL glacial acetic acid at room temperature under an atmosphere of nitrogen was slowly added 0.31 g sodium borohydride. The addition was carried out over a 1.5 hour period through a solid addition funnel between 25-34° C. with ice water cooling. The mixture was stirred at room temperature over night. Then the reaction mixture was added to 80 mL water and the pH was carefully adjusted to 7 by adding solid sodium carbonate. The product was extracted with 80 mL ethyl acetate. The organic layer was separated, washed with brine solution, separated, and dried over magnesium sulfate. The magnesium sulfate was removed by filtration, and the filtrate was concentrated under vacuum to give a brown oil 0.29 g. The product was chromatographed using a Michel-Miller low pressure silica gel column eluted with 9:1 heptane/ethyl acetate. Like fractions were pooled and concentrated under vacuum to give 0.19 g of a tan oil. 1H-NMR d 1.28 (t, 3H), 3.17 (q, 4H), 3.95 (bs, 1H), 4.94-5.21 (md, 1H), 6.59 (d, 1H).

The mixture was stirred, warmed to 40° C. for a one hour period, then concentrated under vacuum to a brown solid 2.0 g. The mixture was chromatographed using a Michel-Miller low pressure silica gel column eluted with 4:1 dichloromethane/heptane.
