New imidazopyridine derivatives having the chemical structure of formula (I) are disclosed; as well as process for their preparation, pharmaceutical compositions comprising them and their use in therapy as inhibitors of Janus Kinases (JAK).
A facile and efficient protocol for palladium-catalyzed Miyaura borylation reaction of chloropyrazines with B2pin2 has been developed. A certain range of difficult-to-access pyrazine boronic esters can be easily prepared from the corresponding chloropyrazines in moderate to good yields.
This invention provides cholesterol absorption inhibitors of Formula I: and the pharmaceutically acceptable salts thereof, wherein R
12
is a hydroxylated alkyl group and R
9
contains a heterocyclic ring. The compounds are useful for lowering plasma cholesterol levels, particularly LDL cholesterol, and for treating atherosclerosis and preventing atherosclerotic disease events.
