Versuchsvorschrift

To a stirred mixture of 3-(5-Aminomethyl-1-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione hydrochloride (1.00 g, 3.20 mmol) and 6-trifluoromethylnicotinoyl chloride (0.65 g, 3.10 mmol) in N,N-dimethylformamide (25 mL), was added triethylamine (0.88 mL, 6.20 mmol) at room temperature under nitrogen. After 1 h, 1N aq. HCl (50 mL) was added and the mixture was stirred for 10 min. The mixture was neutralized with sat. aq. NaHCO3. The product was isolated by filtration, washed with water (50 mL) and dried overnight in vacuo to give N-[2-(2,6-dioxo-piperidin-3-yl)-1-oxo-2,3-dihydro-1H-isoindol-5-ylmethyl]-6-trifluoromethyl-nicotinamide as a white solid (0.73 g, 51% yield): HPLC: Waters Symmetry C18, 5 μm, 3.9×150 mm, 1 mL/min, 240 nm, 40/60 CH3CN/0.1% H3PO4, 2.39 min (97.69%); mp: 240-242° C.; 1H NMR (DMSO-d6) δ 1.92-2.12 (m, 1H), 2.29-2.44 (m, 1H), 2.54-2.70 (m, 1H), 2.81-3.09 (m, 1H), 4.32 (d, J=17.4 Hz, 1H), 4.45 (d, J=17.6 Hz, 1H), 4.65 (d, J=5.7 Hz, 2H), 5.11 (dd, J=5.0, 13.1 Hz, 1H), 7.51 (d, J=7.9 Hz, 1H), 7.59 (s, 1H), 7.71 (d, J=7.7 Hz, 1H), 8.07 (d, J=8.1 Hz, 1H), 8.40-8.60 (m, 1H), 9.22 (s, 1H), 9.56 (t, J=5.8 Hz, 1H), 10.98 (s, 1H); 13C NMR (DMSO-d6) δ 22.49, 31.21, 42.87, 47.14, 51.60, 120.60 (q, J=2.9 Hz), 121.41 (q, J=272 Hz), 122.23, 123.00, 127.20, 130.54, 132.78, 137.49, 142.45, 143.13, 148.1 (q, J=34 Hz), 149.02, 163.74, 167.89, 170.98, 172.85; LCMS: MH=447; Anal Calcd for C21H17N4O4F3+0.25H2O: C, 55.94; H, 3.91; N, 12.43.
