Reaction Steps

A mixture of 4-[(3,4-dichlorophenyl)amino]-6-(methyloxy)quinazolin-7-ol (3.67 g), methyl bromoacetate (0.81 mL), and potassium carbonate (4.66 g) in DMF (21 mL) was stirred at room temperature for 18 hours. The reaction mixture was diluted with ethyl acetate and filtered. The solid was combined with the filtrate and washed with water, dried over sodium sulfate and evaporated to give a brown solid which was recrystallized in methanol to give methyl {[4-[(3,4-dichlorophenyl)amino]-6-(methyloxy)quinazolin-7-yl]oxy}acetate (2.80 g). 1H-NMR (400 MHz; DMSO-d6): 9.62 (s, 1H), 8.46 (s, 1H), 8.24 (s, 1H), 7.94-7.85 (m, 2H), 7.63 (d, 1H), 7.17 (s, 1H), 5.04 (s, 2H), 4.00 (s, 3H), 3.72 (s, 3H); MS (EI) for C18H15N3O4Cl2: 408 (MH+).
