実験手順

To a solution of tert-butyl 3-(1H-1,2,4-triazol-1-ylmethyl)-1-piperazinecarboxylate (29.5 mg, 0.11 mmol) and di-isopropyl-ethyl amine (28.5 mg, 0.22 mmol) in THF (2 ml) was added 5-cyano-2-(3,5-dichlorophenoxy)benzenesulfonyl chloride (40.0 mg, 0.11 mmol). The mixture was stirred at 50° C. overnight. The solvent was removed and the residue was diluted with CHCl3, washed with sat. NaHCO3 aq. and brine. The organic layer was dried over MgSO4. The solvent was evaporated in vacuo, and the resulting residue was purified by prep. TLC (MeOH/CHCl3= 1/10) to give tert-butyl 4-{[5-cyano-2-(3,5-dichlorophenoxy)phenyl]sulfonyl}-3-(1H-1,2,4-triazol-1-yl methyl)-1-piperazine-carboxylate (42.5 mg, 64.9%): HPLC-MS (ESI): Calcd for C25H26Cl2N6O5S [M+H]+ 593, found: 593.
