Versuchsvorschrift
To a stirred solution of m-toluic acid (0.24 g, 1.8 mmol) in DMF (8 mL) in a 40° C. oil bath, was added 1,1′carbonyldiimidazole (0.31 g, 1.9 mmol) and stirred for one hour. To the mixture, 3-(5-aminomethyl-2-methyl-4-oxo-4H-quinazolin-3-yl)-piperidine-2,6-dione hydrogen chloride (0.59 g, 1.8 mmol) was added, and the mixture was stirred for 45 minutes. The solvent was evaporated, and the residue was purified by flash column chromatography (Silica gel, methanol/methylene chloride 4%/96%) to give N-[3-(2,6-dioxo-piperidin-3-yl)-2-methyl-4-oxo-3,4-dihydro-quinazolin-5-ylmethyl]-3-methyl-benzamide as a light green solid (560 mg, 76% yield); HPLC, Waters Symmetry C18, 5 μm, 3.9×150 mm, 1 mL/min, 240 nm, 10/90 CH3CN/0.1% H3PO4, grad. to 95/5 in 5 min, kept 5 min, 6.00 min (99.2%); mp, 263-265° C.; 1HNMR (DMSO-d6)2.18-2.21 (m, 1H, CHH), 2.38 (s, 3H, CH3Ar), 2.59-2.88 (m, 6H, CHCH2, CH3), 4.95-5.12 (m, 2H, CH2NH), 5.26 (dd, J=6, 11 Hz, 1H, CH), 7.33-7.76 (m, 7H, Ar), 8.89 (t, J=5 Hz, 1H, CH2NH), 11.05 (s, 1H, NH); 13C NMR (DMSO-d6) δ 20.83, 20.92, 23.29, 30.60, 42.12, 56.52, 117.65, 123.98, 124.32, 125.40, 127.76, 128.26, 131.85, 133.93, 134.23, 137.65, 141.04, 148.50, 154.80, 161.11, 166.39, 169.53, 172.61.
