Reaction Steps

To a stirred solution of the {2-ethyl-1-[1-(4-methoxyphenyl)-1H-pyrazol-5-yl]butyl}amine (0.77 g, 2.8 mmol) in CH2Cl2 (30 mL) was added triethylamine (0.59 mL, 4.2 mmol) and 5-chlorothiophene-2-sulfonylchloride (0.73 g, 3.4 mmol). The reaction mixture was concentrated in vacuo, diluted with EtOAc, washed twice with 1N HCl, dried (MgSO4), filtered and concentrated in vacuo. The resulting oil was purified by column chromatography (SiO2, EtOAc/hexane, 1:4) to yield a tan solid in 54% yield.
