実験手順

To a solution of 2-(4-methoxy-benzyl)-1,1-dioxo-1λ6-[1,2,5]thiadiazolidin-3-one (64 mg, 0.25 mmol) in anhydrous DMF (2 mL) was added NaH (11 mg, 0.27 mmol) at 0° C. After stirred for 0.5 h at 0° C., a solution of 1-[5-t-butyl-2-(3-chloromethyl-phenyl)-2H-pyrazol-3-yl]-3-(4-fluoro-phenyl)-urea from the previous reaction (100 mg, 0.25 mmol) in anhydrous DMF (2 mL) was added to the reaction mixture, then was stirred overnight at RT. The crude was purified through prepared-HPLC to yield 1-(5-t-butyl-2-{3-[5-(4-methoxy-benzyl)-1,1,4-trioxo-1λ6-[1,2,5]thiadiazolidin-2-ylmethyl]-phenyl}-2H-pyrazol-3-yl)-3-(4-fluoro-phenyl)-urea (45 mg). 1H NMR (DMSO-d6): 8.95 (s, 1H), 8.37 (s, 1H), 7.50-7.54 (m, 3H), 7.36-7.41 (m, 3H), 7.25 (d, J=8.8 Hz, 2H), 7.07 (t, J=8.8 Hz, 2H), 6.87 (d, J=8.4 Hz, 2H), 6.35 (s, 1H), 4.64 (s, 2H), 4.47 (s, 2H), 4.19 (s, 2H), 3.75 (s, 3H), 1.26 (s, 9H). MS (ESI) m/z: 515 (M+H+).
