Abstract
A reaction accelerator for rearrangement of an oxime to an amide consisting of an alkylating agent and an N,N-disubstituted formamide or N,N-disubstituted carboxylic acid amide represented by formula (1): ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different, represent alkyl groups having 1 to 6 carbon atoms or substituted or unsubstituted phenyl groups having 6 to 9 carbon atoms, and R.sup.3 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms. An amide can effectively be produced by rearranging a corresponding oxime in the presence of said reaction accelerator.
