Versuchsvorschrift

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 (0.19 g, 1.2 mmol) in DMF (5 mL) was stirred at room temperature for 18 hours. To the mixture was added 4-(1H-imidazol-2-yl)-phenylamine (0.17 g, 1.1 mmol) at room temperature, and the mixture was stirred at 60° C. for 1d. To the mixture was added water (25 mL) and ethyl acetate (20 mL). The mixture was stirred at room temperature for 2 h. The suspension was filtered and the solid was washed with water (20 mL), ethyl acetate (20 mL) and water (20 mL) to give a solid. The solid was purified with Prep HPLC to give 1-[2-(2,6-dioxo-piperidin-3-yl)-1-oxo-2,3-dihydro-1H-isoindol-5-ylmethyl]-3-[4-(1H-imidazol-2-yl)-phenyl]-urea as a white solid (150 mg, 30% yield): HPLC: Waters Symmetry C18, 5 μm, 3.9×150 mm, 1 mL/min, 240 nm, 5/95 grad 95/5 in 5 min CH3CN/0.1% H3PO4, 4.41 min (95.9%); mp: 190-192° C.: 1H NMR (DMSO-d6) δ 1.91-2.08 (m, 1H, CHH), 2.27-2.47 (m, 1H, CHH), 2.54-2.66 (m, 1H, CHH), 2.81-3.01 (m, 1H, CHH), 4.31 (d, J=17.4 Hz, 1H, CHH), 4.38-4.52 (m, 3H, CHH, CH2), 5.11 (dd, J=5.0, 13.3 Hz, 1H, NCH), 6.78 (t, J=6.0 Hz, 1H, NH), 7.33-7.76 (m, 9H, Ar), 8.17 (s, 1H, HCOOH), 8.67 (s, 1H, NH), 10.99 (s, 1H, NH); 13C NMR (DMSO-d6) δ 22.41, 31.10, 42.69, 47.02, 51.49, 114.17 (br), 117.80, 121.79, 122.84, 124.55, 126.81, 126.98, 130.19, 135.46, 138.55, 142.31, 144.83, 155.14, 163.19 (HCOOH), 167.88, 170.92, 172.77; LCMS MH=459: Anal.
