The condensation of diketone (I) with hydrazine (II) in refluxing EtOH gave pyrazole (III). Carboxylic acid (IV) was then obtained by oxidative cleavage of the furan ring with KMnO4. After conversion of (IV) to the corresponding acid chloride (V), coupling with the biphenyl amine (VI) provided amide (VII). Ring closure of the fluoronitrile group with acetamidine hydrochloride (VIII) with concomitant deprotection of the N-tert-butyl group furnished the title aminoquinazoline derivative.
