, p. 8121 - 8124 (2013)
2-N-Piperidinopyrazine, 2-N-(3-methyl)piperidinopyrazine and 2-N-(4-methyl)piperidinopyrazine were synthesized by reacting 2-chloropyrazine with piperidine, 3-methylpiperidine, 4-methylpiperidine respectively. The structures of these compounds were confir

A mild and highly efficient catalytic amination procedure for chloroheteroarenes at ambient temperature using the Pd/PTABS catalytic system is reported. The protocol is selective for the amination of chloroheteroarenes using secondary amines such as piperidine, pyrrolidine, and several others. The exceptional mildness of the developed protocol is beneficial for the synthesis of a crucial Buparlisib intermediate as well as the formal synthesis of Alogliptin in competitive yields.

C-N bond forming reactions are important in organic chemistry. A thin film microfluidic vortex fluidic device (VFD) operating under confined mode affords N-aryl compounds from 2-chloropyrazine and the corresponding amine, without the need for a transition

Inhibition of rho kinase (ROCK) has been recognized as an important target for a number of diseases, including glaucoma. Herein we report SAR development around two hits from a kinase library that led to the discovery of the ROCK inhibitor compound 38. In vitro and in vivo analysis of this compound, including its effects in a monkey model of glaucoma will be discussed.
Aminopyrazine analogs for treating glaucoma and other rho kinase-mediated diseases and conditions
-
Page/Page column 27, (2008/06/13)
Methods for using aminopyrazine analogs to treat rho kinase-mediated diseases or rho kinase-mediated conditions, including controlling intraocular pressure and treating glaucoma, are disclosed. Ophthalmic pharmaceutical compositions useful in the treatment of eye diseases such as glaucoma, and additionally useful for controlling intraocular pressure, the compositions comprising an effective amount of aminopyrazine analogs, are also disclosed.
Efficient nucleophilic substitution reactions of pyrimidyl and pyrazyl halides with nucleophiles under focused microwave irradiation
Cherng, Yie-Jia
, p. 887 - 890 (2007/10/03)
Rapid nucleophilic displacement reactions of 2-chloropyrimidine, 2-bromopyrimidine, 5-bromopyrimidine and chloropyrazine with nucleophiles under microwave irradiation was complete within several minutes with yields up to 99%. The method using microwave irradiation is superior to the classical heating processes.
