A Concise and Efficient Synthesis of [2-Methyl-5-methylsulfonyl-4-(pyrrol-1-yl)benzoyl]guanidinium Methanesulfonate (Eniporide)
摘要:
A new synthesis of the benzoylguanidine-type Na+/H+ antiporter inhibitor eniporide (7) is described. Starting from 2-bromo-5-fluorotoluene (1), aromatic substituents were introduced by methanesulfonylation, Pd-catalyzed carboxylation with CO, and halogen-pyrrole exchange. Guanidine acylation was performed using Mukaiyama's procedure.
