Application

2, 3-dichloropyrazine is an effective substrate for the synthesis of aloe base, a potent cyclin-dependent kinase. It is mainly used as a medical intermediate.

2,3-Dichloropyrazine is a substrate used for an efficient synthesis of aloisine (A575450), a potent cyclin-dependent kinase.

Selective monosubstitution of this substrate provided an efficient synthesis of alloisines, potent cyclin-dependent kinases.
