Studies on pyrazines. 35 [1]. An improved synthesis of bromopyrazines from hydroxypyrazines
Sato, Nobuhiro,Narita, Nobuhiko
, p. 783 - 786 (2007/10/03)
The synthesis of bromopyrazines from hydroxypyrazines was successfully effected by the procedure via trimethylsilyloxypyrazines, the sequence of which proceeds under mild conditions and does not require the isolation of intermediate.
