摘要

Abstract:-Tosyloxyketone 2, obtained through hypervalent iodine oxidation of enolizable ketones using [hydroxy (tosyloxy) iodo] benzene (HTIB) in acetonitrile, on treatment with 2- aminopyrimidine 3 generates regioselectively 2-arylimidazo [1, 2-] pyrimidine 6 which upon subsequent treatment with bromine undergoes electrophilic substitution at position-3 to yield 3-bromo-2-arylimidazo [1, 2-] pyrimidine 8.
