## Abstract An exception of Eschweiler‐Clarke methylation was found for α‐amino amides. The α‐amino amides on treatment with formaldehyde and formic acid produce cyclocondensation products, imidazolidin‐4‐ones, but __N__‐methylation process becomes important when three substituents of the α‐amino a
