An intriguing transesterification reaction is reported here for the first time. Different carbocyclic N‐1 alkoxycarbonyl methyl substituted hydantoins were treated with alkyl halides and sodium hydride as a base, in the presence of N,N‐dimethylformamide. Under these typical N‐alkylation reaction ...
