The Uses of 2-Chloropyrimidine

2-Chloropyrimidine is a useful reagent in the preparation of antivirals and other biologically active compounds. It was used in the synthesis of 4?-(1,1?-(5-(2-methoxyphenoxy)-[2,2?-bipyrimidine]-4,6-diyl)bis(1H-pyrazol-3,1-diyl)) dianiline fluorescent dye, biosensor for protein assay, 2-amino-4-heteroarylpyrimidines, cis- and trans-octahydropyrrolo[2,3]pyridine derivatives.

General Description

2-Chloropyrimidine undergoes cobalt-catalyzed cross-coupling reaction with aryl halides.

Purification Methods

It has been recrystallised from *C6H6, pet ether or a mixture of both. It sublimes at 50o/18mm and can be distilled in a vacuum. [IR: Short & Thompson J Chem Soc 168 1952, Boarland & McOmie J Chem Soc 1218 1951, Beilstein 23/5 V 343.]
