摘 要:以2-氨基-4-硝基苯甲酸和甲酰胺為原料,經(jīng)Niementowski、氯代、烴化反應合成4-苯基氨基-7-硝基喹唑啉鹽酸鹽,再經(jīng)鐵粉還原得4-苯基氨基-7-氨基喹唑啉。目標化合物的結構經(jīng)1H NMR、IR、MS譜表征。前三步反應采用微波輻助合成,大大縮短了反應時(shí)間,提高了反應速率和收率。 |

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 |
