Procedure
Using the methods described above in Example 12, but substituting 2-ethylbenzenethiol for 3-(4-mercaptophenyl)-2,2-dimethylpropionic acid ethyl ester in step a, 2-[4-(2-ethylbenzenesulfonyl)phenyl]-1,1,1-trifluoropropan-2-ol was prepared. 1H NMR (CDCl3, 400 MHz) δ 8.19 (dd, J=1.3 Hz, 8.0 Hz, 1H), 7.84 (d, J=8.5 Hz, 2H), 7.73 (d, J=8.5 Hz, 2H), 7.56 (m, 1H), 7.40 (m, 1H), 7.32 (d, J=7.6 Hz 1H), 3.03 (s, 1H), 2.58 (q, J=7.4 Hz, 2H), 1.77 (s, 3H), 1.03 (t, J=7.5 Hz, 3H). The racemic product was resolved by chiral HPLC. The flow rate was 20 mL/min on a Chiralcel OD-H 20 mm i.d.×250 mm, 5μ column (Daciel Chemical Industries LTD), using isopropyl alcohol/hexanes (7/93) as the eluent.
