実験手順

{(2,5-Dimethoxy-benzenesulfonyl)-[4-(4-isopropyl-phenyl)-thiazol-2-yl]-amino}-acetic acid tert-butyl ester was prepared following general procedure F using N-[4-(4-isopropyl-phenyl)-thiazol-2-yl]-2,5-dimethoxy-benzenesulfonamide (126 mg, 0.3 mmol), tert-butyl bromoacetate (90.4 μL, 98%, 0.6 mmol), potassium carbonate (124 mg, 0.9 mmol) and DMF (1 mL). Purification (silica gel, ethyl acetate/hexanes 1:4) gave the product compound (111 mg, 0.208 mmol). LCMS m/z: 533 (M+1)+.
