ions in the extracellular fluid. For this reason, it was necessary to synthesize a quaternary salt of gabapentin 1. We now describe an efficient methodology for the synthesis of 1-(trimethylammoniummethyl)cyclohexaneacetic acid iodide (2) using a four-step reaction sequence free of time consuming chromatography in 81% overall isolated yield starting from gabapentin (see structures in Scheme 1).
