ABSTRACT A novel and practical strategy for the synthesis of vonoprazan fumarate 1, a novel potassium-competitive acid blocker, has been developed. Vonoprazan fumarate was obtained through a four-step process starting from 5-(2-fluorophenyl)-1H-pyrrole-3-carboxylate and including ester hydrolyzing, methylamine substitution, sulfonyl chloride substitution, and amide reduction. Key to the strategy is
