Versuchsvorschrift

EX-66° C.) A solution of 3-(4chloro-3-ethylphenoxy)aniline (1.7 g, 6.9 mmol) was prepared in cyclohexane (13 mL). A solution of crude 3-pentafluoroethyl benzylbromide (1 g, 3.5 mmol) product from EX-660B in cyclohexane (10 mL) was added dropwise over 3 min. The reaction mixture was refluxed under N2 for 24 h and then was cooled to room temperature. The mixture was diluted with Et2O and saturated aqueous NaHCO3. The layers were separated, and the aqueous layer was extracted with Et20. The organic layer was washed with brine, dried with anhydrous MgSO4, filtered and concentrated in vacuo. The residue was purified by chromatography on silica gel eluting with hexanes in ethyl acetate (95:5) which gave 0.56 g (35%) of the desired N-[3-(4-chloro-3-ethylphenoxy)phenyl][[3-(pentafluoroethyl)phenyl] methyl]amine product as an amber oil. 1H NMR (CDCl3) δ 7.53 (m, 4H), 7.27 (d, 1H), 7.15 (t, 1H), 6.93 (d, 1H), 6.77 (dd, 1H), 6.41 (tt, 2H), 6.30 (t, 1H), 4.41 (s, 2H), 2.73 (q, 2H), 1.23 (t, 3H). 13C NMR (CDCl3) δ 158.6, 156.1, 143.4, 141.3, 140.2, 131.3, 130.7, 130.4, 129.4, 128.1, 120.4, 117.8, 108.8. 103.9, 48.5, 27.5, 14.1. 19F NMR (CDCl3) δ −85.1 (s, 3F), −115.2 (s, 2F).
