실험 절차

To a stirred solution of 2-chloro-N-[2-(3-methanesulfonyl-phenyl)-thiazol-5-ylmethyl]-benzenesulfonamide (30 mg) in N,N-dimethylacetamide (0.6 mL) were added benzyl bromide (13 mg) and cesium carbonate (26 mg). The mixture was stirred overnight at r.t. The mixture was diluted with ethyl acetate and washed with water. The organic phase was dried (MgSO4), filtered and concentrated under reduced pressure. The product was purified by chromatography (SiO2, cyclohexane/ethyl acetate 1:0 to 1:1) to give N-benzyl-2-chloro-N-[2-(3-methanesulfonyl-phenyl)-thiazol-5-ylmethyl]-benzenesulfonamide as a colorless solid. MS: 534.8 ([M+H]+)
