The present disclosure provides certain bicyclic heteroaryl compounds that inhibit ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) enzymatic activity and are therefore useful for the treatment of diseases and conditions modulated at least in part by ENPP1. In some embodiments, the bicyclic heteroaryl compounds includes those of Formula (I). Also provided herein are pharmaceutical compositions containing such compounds and processes for preparing such compounds.
Abstract Benzal chlorides and benzal bromides were conveniently synthesized by reaction of aryl aldehydes with a Vilsmeier type reagent formed in situ by reduction of CC14 or CBr4 in dimethylformamide (DMF) as solvent.
