Versuchsvorschrift

A mixture of 1-[2-({4-[(E)-2-(4-fluorophenyl)vinyl]phenyl}sulfonyl)phenyl]-2-hydroxyethanone (Example 167, 20 mg, 0.05 mmol) and sodium borohydride (10 mg, 0.26 mmol) in methanol (2 mL) and dichloromethane (0.5 mL) was stirred at room temperature for 30 minutes. The reaction was quenched with water and concentrated in vacuo. The residue was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over MgSO4 and concentrated in vacuo. δH (500 MHz, d6 DMSO): 8.04 (1H, d, J=7.9 Hz), 7.84–7.79 (4H, m), 7.74 (1H, d, J=7.7 Hz), 7.70–7.67 (3H, m), 7.53 (1H, t, J=7.3 Hz), 7.44 (1H, d, J=16.3 Hz), 7.29 (1H, d, J=16.4 Hz), 7.23 (2H, t, J=8.6 Hz), 5.36 (2H, s), 4.71 (1H, s), 3.32 (1H, s), 3.17 (1H, s).
