Reaction Steps
THF (5 ml) and NaH (60% disp in oil, approx. 28 mg) is added to a dry flask maintained under inert atmosphere at room temperature. 3-Chlorophenol (0.09 g) is added as a soln. in THF (1 mL) and stirring is continued until the solution became clear. 4-Chloro-6,7-dimethoxyquinazoline is added all at once (as the solid) and stirring was maintained overnight at RT. The solution is partitioned between CH2Cl2 and 5% NaOH. The organic layer is washed with brine, dried (Na2SO4) and concentrated. Flash column chromatography (40% EtOAc/Hex) provided the pure compound. An analytical sample is obtained by recrystallization from EtOAc/Hex to provide 4-(3-chlorophenoxy)-6,7-dimethoxyquinazoline (0.05 g), white needles, m.p. 152°-153° C.
