Procedure
5-{3-[5-(3.4-Dichloro-phenyl)-1-(4-methoxy-phenyl)-1H-pyrazole-3-yl]-2-m-tolyl-propylsulfanyl}-1H-1,2,4]-triazole. To a suspension of sodium hydride (4.0 mg, 60% dispersion in oil) in N,N-dimethylformamide (1.0 mL) at 0° C. was added a solution of 2H-[1,2,4]triazole-3-thiol (10.0 mg, 0.1 mmol, 1.1 equiv) in N,N-dimethylformamide (1.0 mL). The mixture was stirred at 0° C. for 30 min then a solution of 3-(3-bromo-2-m-tolyl-propyl)-5-(3,4-dichloro-phenyl)-1-(4-methoxy-phenyl)-1H-pyrazole (48 mg, 0.09 mmol, 1.0 equiv) in N,N-dimethylformamide (1.0 mL) was added. The reaction mixture was brought to room temperature then was stirred for 2 h. The reaction was quenched with satd aq ammonium chloride (1.0 mL), and the resulting mixture was diluted with water (10.0 mL), and extracted with ethyl acetate (3×10 mL). The combined organic layers were washed with water (10 mL) then brine (10 mL), dried (Na2SO4), and concentrated under reduced pressure. The crude residue was purified by reversed-phase HPLC to yield the title compound (39 mg, 80%). HPLC: Rt=3.26 (Method B).
