実験手順

To a solution of (2S)-2-methyl-1-[(6-methyl-3-pyridinyl)carbonyl]piperazine (Description 13) (100 mg, 0.456 mmol) in DMF (10 ml) was added 4-[(difluoromethyl)oxy]benzenesulfonyl chloride (133 mg, 0.547 mmol). Finally DIPEA (0.239 ml, 1.368 mmol) was added and the reaction mixture was stirred at room temperature for 20 h. Solvent was removed by evaporation, the residue was dissolved in ethyl acetate and the solution washed with saturated aqueous NaHCO3. The organic layer was dried over MgSO4, filtered and evaporated to dryness and the residue was purified by MDAP to yield the title compound (72 mg) as a white powder.
