실험 절차

The title compound was prepared from the first eluting isomer diethyl (1S,2S,3R,4S)-3-(2-methylphenyl)-4-hydroxycyclohexane-1,2-dicarboxylate (step G) and (1S)-1-[3,5-bis(trifluoromethyl)phenyl]ethyl-2,2,2-trichloroethanimidoate (Example 6, step E) according to the procedure of Example 6, step F. 1H-NMR (CDCl3): δ: 7.65 (1H, s), 7.15 (2H, s), 7.08–6.92 (4H, m), 4.25 (1H, q, J=6.0 Hz), 4.20–4.10 (2H, m), 3.85–3.66 (2H, m), 3.42 (1H, m), 3.21 (1H, t), 2.90–2.79 (2H, m), 2.35 (1H, m), 2.25 (1H, m), 2.22 (3H, s), 1.69–1.56 (2H, m), 1.30 (3H, d, J=6.0 Hz), 1.23 (3H, t, J=7.2 Hz), 0.77 (3H, t, J=7.2 Hz). Unreacted starting alcohol could be recovered by flushing the column with EtOAc and reused in the above reaction.
