Procedure

A mixture of compound 2-(4-(2-aminoethoxy)-3,5-dimethylphenyl)-5,7-dimethoxyquinazolin-4(3H)-one (0.060 g, 0.16 mmol), p-toluoyl chloride (0.028 mL, 0.21 mmol), and PS-DIEA (0.057 g, 0.21 mmol) in CH2Cl2 (4.0 mL) was stirred at room temperature for 16 h. The mixture was filtered, washed with CH2Cl2 and the solvent was removed under reduced pressure. The resulting residue was chromatographed on silica gel to yield N-(2-(4-(5,7-Dimethoxy-4-oxo-3,4-dihydroquinazolin-2-yl)-2,6-dimethylphenoxy)ethyl)-4-methylbenzamide (0.037 g, 51%) as an off-white solid: 1H NMR (300 MHz, DMSO-d6) δ 11.80-11.00 (s, 1H), 8.69 (t, J=5.43 Hz, 1H), 7.88 (s, 2H), 7.79 (d, J=8.19 Hz, 2H), 7.28 (d, J=8.00 Hz, 2H), 6.73 (d, J=2.31 Hz, 1H), 6.51 (d, J=2, 31 Hz, 1H), 3.94 (t, J=5.59 Hz, 2H), 3.88 (s, 3H), 3.84 (s, 3H), 3.72-3.60 (m, 2H), 2.36 (s, 3H), 2.27 (s, 6H); MS (APCI) m/z 488 [M+H]+.
