The synthetic route is as follows., HPLC of Formula: C9H13NO
To a mixture of 1-(4-chlorobenzyl)-3-(ethoxycarbonylmethyl)-6-iodoquinazoline-2,4-dion (200 mg, 0.4 mmol), palladium acetate (13.5 mg, 0.06 mmol), 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (52.2 mg, 0.09 mmol), cesium carbonate (261 mg, 0.8 mmol) and dioxane mL) was added 4-isopropoxyaniline (0.071 ml, 0.48 mmol) under nitrogen atmosphere, and the resulting mixture was heated at reflux for 2 hours. The reaction mixture was poured into a mixture of water (1.00 mL) and 5% aqueous citric acid (10 mL), and the resulting mixture was extracted with ethyl acetate (100 mL). The extract was washed by water (100 mL), dried over anhydrous sodium sulphate, and concentrated in vacuo. The resulting residue was purified by silica gel column chromatography (ethyl acetate/hexane), and the residue was precipitated by hexane to give 1-(4-chlorobenzyl)-3-(ethoxycarbonylmethyl)-6-(4-isopropoxyphenylamino)-quinazoline-2,4-dion (7.7 mg, Yield: 3.7%) as yellow solid. 1H-NMR (delta ppm TMS/CDCl3): 1.28 (3H, t, J=7.2 Hz), 1.33 (6H, d, J=6.0 Hz), 4.24 (2H, q, J=7.2 Hz), 4.74 (1H, m), 4.88 (2H, s), 5.29 (2H, s), 5.61 (1H, s), 6.84 (2H, d, J=8.7 Hz), 6.91 (1H, d, J=9.0 Hz), 7.01 (2H, d, J=8.7 Hz), 7.11 (1H, dd, J=3.0, 9.0 Hz), 7.19 (2H, d, J=8.7 Hz), 7.30 (2H, d, J=8.7 Hz), 7.68 (1H, d, J=2.7 Hz).
