A microwave catalysis in the aqueous phase a method of preparing Quinazolinone compounds

The invention discloses a method for preparing quinazolinone in water phase through microwave catalysis. The method comprises the step: by utilizing a water-soluble coordination compound (such as 8-hydroxyquinoline) as a catalyst, carrying out high-efficiency microwave catalysis on the reaction of 2-halogenated benzaldehyde and amidine salts in pure water phase. The invention relates to a method for preparing a quinazolinone compound, which is environment-friendly, simple and convenient to operate, safe and low-cost, and high-efficiency. Compared with the prior art, the method not only can be applicable to a great deal of functional groups, high in yield, fewer in side products, but also is simple and safe to operate, low in cost, and environment-friendly.
