Procedure

To phenylhydrazine (50 uL) in toluene-HOAc (2:1, 2 mL) was added 2-(4-fluorophenyl)-1-(4-(methylsulfonyl)phenyl)ethanone (105 mg) (prepared from 4-(methylthio)benzaldehyde and 4-fluorobenzyl chloride by the same method as described in Step 1 of Example 4). After 1 hr at 85° C., the reaction mixture was extracted with EtOAc and HCl. After drying over NaSO4 and evaporation in vacuo the title compound was purified by flash chromatography (67 mg).
