Reaction Steps

A mixture of compound 2-(4-(2-aminoethoxy)-3,5-dimethylphenyl)-5,7-dimethoxyquinazolin-4(3H)-one (0.10 g, 0.27 mmol), methylisocyanate (0.020 g, 0.35 mmol), and Et3N (0.034 g, 0.35 mmol) in THF (4.0 mL) was stirred at room temperature for 16 hours. 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 the title compound (0.082 g, 71%) as a white solid: MS (APCI) m/z 449 [M+Na]+.
