Abstract:A microwave-assisted preparation method of the protein tyrosine kinase inhibitors aniline quinazoline was reported. 4-Anilino-7-nitroquinazoline hydrochloride salt was synthesized using 2-amino-4-nitro benzoic acid as the starting material through the Niementowski reaction,chlorination and alkylation,and then gave the target product through iron reduction reaction. The structure of the target compound was confirmed by 1H NMR、IR and MS. The microwave-assisted synthesis method in the former three-step reactions can not only reduce reaction time,but also increase the reaction rate and yield of product.
Key words:tyrosine kinase JAK inhibitors;4-anilino-7-aminoquinazoline;microwave synthesis
