実験手順

A mixture of 3-(5-aminomethyl-1-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione methanesulfonic acid salt (0.40 g, 1.1 mmol) and CDI (0.21 g, 1.3 mmol) in DMF (5 mL) was stirred at room temperature for 18 h. To the mixture was added 3-(1H-benzoimidazol-2-yl)-4-chloro-phenylamine (0.32 g, 1.3 mmol) at room temperature, and the mixture was stirred at 100° C. for 18 hours. To the mixture was added water (25 mL) and ether (20 mL). The mixture was stirred at room temperature for 2 h. The solvent was decanted. The solid was purified with Prep HPLC to give 1-[3-(1H-benzoimidazol-2-yl)-4-chloro-phenyl]-3-[2-(2,6-dioxo-piperidin-3-yl)-1-oxo-2,3-dihydro-1H-isoindol-5-ylmethyl]-urea as a white solid (130 mg, 22% yield): HPLC: Waters Symmetry C18, 5 μm, 3.9×150 mm, 1 mL/min, 240 nm, 20/80 CH3CN/0.1% H3PO4, 4.44 min (99.2%); mp: 275-277° C.; 1H NMR (DMSO-d6) δ 1.90-2.10 (m, 1H, CHH), 2.23-2.46 (m, 1H, CHH), 2.54-2.68 (m, 1H, CHH), 2.80-3.02 (m, 1H, CHH), 4.31 (d, J=17.4 Hz, 1H, CHH), 4.37-4.51 (m, 3H, CHH, CH2), 5.11 (dd, J=5.0, 13.3 Hz, 1H, NCH), 6.89 (t, J=5.9 Hz, 1H, NH), 7.23 (d, J=4.5 Hz, 2H, Ar), 7.40-7.76 (m, 7H, Ar), 8.07 (d, J=2.5 Hz, 1H, Ar), 9.02 (s, 1H, NH), 10.98 (s, 1H, NH), 12.64 (br. s., 1H, NH); 13C NMR (DMSO-d6) δ 22.39, 31.10, 42.75, 47.02, 51.48, 111.62, 118.88, 120.11, 120.62, 121.55, 121.83, 122.56, 122.85, 126.85, 129.79, 130.23, 130.35, 134.56, 139.56, 142.29, 143.00, 144.58, 149.12, 154.96, 162.96, 167.86, 170.91, 172.76; LCMS MH=543, 545; Anal.
