Reaction Steps

An analogous reaction to that described in example 137b, but starting with 7-fluoro-5-isopropoxyquinazolin-4(3H)-one (444 mg, 2 mmol) and 2-methoxyethanol (0.32 ml, 4.06 mmol) and heating at 120° C. for 1.5 hours yielded 5-isopropoxy-7-(2-methoxyethoxy)quinazolin-4(3H)-one (155 mg, 28% yield) as a beige solid:
