A New Convenient Synthesis of 2-Aryl- and 2-Heteroaryloxazolopyridines
Flouzant, Christine,Guillaumet, Gerald
, p. 64 - 66 (2007/10/02)
Several 2-aryl- and 2-heteroaryloxazolopyridines were synthesized in high yields from 3-(arylcarbonylamino)-2-chloropyridines by heating in the presence of trimethylsilylpolyphosphate ester.
