2,3-Dichloroquinoxaline → 2-benzyl-3-chloroquinoxaline

Participants

Reaction Steps

Intermediate 3 can be prepared from the starting material 2,3-dichloroquinoxaline 1 following the reaction in Scheme 1. In this manner, quinoxaline 1 can be reacted with benzylmagnesium chloride in THF to afford 2-benzyl-3-chloroquinoxaline 2. 2-Benzylquinoxalines can also be prepared by reaction with alternative alkylating reagents, such as, but not limited to, benzyllithium. 2-Benzyl-3-chloroquinoxaline 2 can be reacted with cyanide to obtain intermediate 2-benzyl-3-cyanoquinoxaline 3.
