Optimization of a 5-oxopyrrolopyridine series based upon structure-activity relationships (SARs) developed from our previous efforts on a number of related bicyclic series yielded compound 2s (BMS-767778) with an overall activity, selectivity, efficacy, PK, and developability profile suitable for progression into the clinic. SAR in the series and characterization of 2s are described.
