Reaction Steps

(6-Hydrazonomethylquinazolin-4-yl)-(3-methyl-4-phenoxyphenyl)amine is prepared by adding hydrazine (50 mg, 1.00 mmol) to a solution of 4-(3-methyl-4-phenoxyphenylamino)-quinazoline-6-carbaldehyde (250 mg, 0.70 mmol) in a 1:1 mixture of DCM:IPA (6 mL). After stirring at room temperature for 4 hours, excess hydrazine and solvent are removed under reduced pressure to give the desired hydrazone as a brown solid which is carried forward without purification.
