Triethylamine → 5-Chloro-N-{2-ethyl-1-[1-(4-fluorobenzyl)-1H-1,2,4-triazol-5-yl]butyl}thiophene-2-sulfonamide

Participants

Reaction Steps

To a stirred solution of the {2-ethyl-1-[1-(4-fluorobenzyl)-1H-1,2,4-triazol-5-yl]butyl}amine (0.133 g, 0.481 mmol) in CH2Cl2 (10 mL) was added Et3N (0.10 mL, 0.72 mmol) followed by 5-chlorothiophene-2-sulfonyl chloride (0.115 g, 0.529 mmol). The reaction mixture was stirred for 18 h, concentrated in vacuo, partitioned between 0.1N HCl and EtOAc. The organic extracts were dried (MgSO4), filtered and concentrated in vacuo. Column chromatography (SiO2, EtOAc/hexane, 3:7) provided pure material as a yellow solid in 60% yield.
