Abstract
A new short and highly efficient synthesis of (5)‐2,3‐dimethoxy‐N[(1‐ethyl‐2‐pyrrolidinyl)methyl]‐5‐iodobenzamide (epidepride, 1) from 3‐methoxy‐salicylaldehyde (o‐vanillin, 2) and 3‐methoxysalicyclic acid (6) was achieved by employing a new iodination method with iodine monochloride and iodine nitrate under basic conditions.
