Tegoprazan, a selective potassium-competitiveacidblocker, was approved in 2018 in the Republic of Korea for the treatment of gastroesophageal reflux disease (GERD), erosive esophagitis (EE), and nonerosive reflux disease (NERD). The complexity of tegoprazan, which contains a 4,6-disubstituted 1H-benzo[d]imidazole core and a chiral chromanol moiety, makes it a challenging molecule to prepare on a
