A number of pre-designed C-7-substituted-2-morpholino-N-(pyridin-2-ylmethyl)quinazolin-4-amine were synthesized for the first time using Palladium catalyzed suzuki reactions in microwave with a ligand X-PHOS. A key intermediate 7-chloro-2-morpholino-N-(pyridin-2-ylmethyl)quinazolin-4-amine (7) was synthesized and treated with 20 different boronic acids to give 20 derivatives in good to excellent yields. All these compounds were tested for their antibacterial properties against four strains of bacterial microorganisms including two gram-positive and two gram-negative species. Out of twenty compounds, five compounds, compound 8, 16, 23, 24, 25 showed better activity against gram negative as well as gram positive strains.
