Substituted pyrazines and a process for producing the same |
| abstract |
Described include (1) a substituted pyrazine compound of general formula (VIII): n nand (2) a process for producing the substituted pyrazine compound of general formula (VIII), where R 1 is hydrogen, a halogen, a substituted or unsubstituted hydrocarbon group, or a substituted or unsubstituted heterocyclic group, and R 4 is a protecting group. The process comprises (1) the step of reacting 2-amino-3,5-dibromo-6-chloropyrazine with R 1 MgX and ZnCl 2 in the presence of a palladium catalyst to produce a compound of general formula (V); (2) the step of reacting the compound of general formula (V) with a compound of general formula (VI) to produce a compound of general formula (VII); and (3) the step of reacting the compound of formula (VII) with tributyl(vinyl)tin in the presence or a palladium catalyst to given the compound of general formula (VIII). |
