실험 절차

To a solution of 2-pyrrolidinone (26.5 mg, 0.312 mmol) in DMSO (1 mL) and t-BuOK (48.9 mg, 0.436 mmol), that had been stirred for 40 min at ambient temperature, was added a solution of 3-(3-bromomethylphenyl)-5-iso-butyl-N-tert-butylthiophene-2-sulfonamide (92.3 mg, 0.208 mmol; see Example 1(e)) in DMSO (1 mL) dropwise. The reaction mixture was stirred for 1 h at ambient temperature and then diluted with CH2Cl2 (15 mL). The organic layer was washed with water, dried (over anhydrous MgSO4), concentrated in vacuo, and the residue purified by flash chromatography using MeOH:CH2Cl2 (2:98) as eluent to give the sub-title compound in 77% yield as a colourless syrup (72.3 mg, 0.161 mmol).
