反応手順

A solution of phenylhydrazine (203 uL, 1.73 mmol) and 1-(4-fluorophenyl)-2-(4-(methylsulfonyl)phenyl)ethanone (510 mg, 1.73 mmol) (Step 2) in a mixture of toluene/HOAc (2:1; 5 mL) containing 1 drop of methanesulfonic acid was stirred at r.t. overnight. The reaction mixture was diluted with EtOAc and was washed successively with H2O, 1M NaOH, H2O and dried. Evaporation of the solvent gave a residue which was purified by silica gel chromatography using EtOAc/hexane (1:3+10% CH2Cl2) as eluent to afford 339 mg of the title compound.
