Pharmacology

Ibutilide is an Antiarrhythmic.

How it is made

The synthesis starts with a Friedel-Crafts acylation of methanesulfonanilide with succinic anhydride in presence of AlCl3 yielding 4-[(methylsulfonyl)amino]-gamma-oxobenzenebutanoic acid, which is treated with N-ethylheptylamine and dicyclohexylcarbodiimide (DCC) in DMF to give the corresponding amide. Reduction with LiAlH4 in THF in the last step provides the desired drug substance.
