A general and facile one-pot amination procedure for the synthesis of 2-aminopyridines from the corresponding pyridine-N-oxides is presented as a mild alternative to S(N)Ar chemistry. A variety of amines and heterocyclic-N-oxides participate effectively in this transformation which uses the phosphonium salt, PyBroP, as a means of substrate activation.
One aspect of the invention relates to a series of new PCSK9 inhibitor compounds comprising piperidine ring structures, including compounds of formula (I) and/or pharmaceutically acceptable salts thereof. Another aspect of the invention relates to methods of treating PCSK9 receptor related diseases comprising administration of one or more compounds of formula (I) or a pharmaceutically acceptable salt thereof.
