The present invention relates to the use of bi-cyclic pyrimidines as inhibitors of HCV replication as well as their use in pharmaceutical compositions aimed to treat or combat HCV infections. In addition, the present invention relates to processes for preparation of such pharmaceutical compositions. The present invention also concerns combinat ions of the present bi-cyclic pyrimidines with other anti-HCV agents.

the product by astronger base in the reaction coordinate diagram. On theother hand, when the leaving group was changed from 2,4-dinitrophenoxide to picrate, the ρ value decreased but the βvalue increased. The results are in conflict with the predic-tion of the reaction coordinate diagram because both ρ and βvalues should be decreased with a better leaving group. Theunusual changes in the transition-state
Elimination Reactions of (E)-2,4,6-Trinitrobenzaldehyde O-Aryloximes Promoted by R<sub>3</sub>N/R<sub>3</sub>NH<sup>+</sup>in 70 mol% MeCN(aq). Effect of β-Aryl Group the Nitrile-Forming Transition-State

Nitrile-forming eliminations from (1) promoted by in 70 mol % MeCN(aq) have been studied kinetically. When X = , the reactions exhibited second-order kinetics as well as Brnsted = 0.63 and = 0.34-0.46, and an E2mechanism is evident. As the leavinggroup was made poorer (X = H, Cl, and ), Brnsted value increased from 0.63 to 0.85-0.89 without much change in the value E2, indicating that structure of

Improved reagents and methods of amination are provided. The reagents are phenyl hydroxylamines containing one nitro and at least one CF3 substituent on the phenyl moiety.
Compounds in which a pyrimidine nucleus is bridged at the 5 and 6 position and are further substituted at positions 2 and 4 with substituents comprising aromatic moieties are useful in treating subjects with conditions ameliorated by inhibition of TGFβ activity.
