Procedure

To a stirred solution of [1-(1-benzyl-1H-imidazol-2-yl)-2-ethylbutyl]amine (448 mg, 1.74 mmol) in CH2Cl2 (15 mL) was added triethylamine (0.36 mL, 2.6 mmol) and 5-chlorothiophene-2-sulfonylchloride (453 mg, 2.09 mmol). The mixture was stirred for 3.5 h and then diluted with EtOAc, washed twice with 1N HCl, dried over MgSO4, filtered and concentrated in vacuo. The resulting oil was purified by column chromatography (SiO2, CHCl3, then 1% MeOH/CHCl3 to 2% MeOH/CHCl3) to yield a white solid in 59% yield.
