    Abstract: A method of producing an N,N-disubstituted amide of the present invention is a method of reacting a nitrile with an alcohol in the presence of a catalyst, wherein the nitrile is a compound represented by R1CN (R1 represents an alkyl group having 10 or less carbon atoms or an aryl group having 10 or less carbon atoms), wherein the alcohol is a compound represented by R2OH (R2 represents an alkyl group having 10 or less carbon atoms), wherein the catalyst is a metal salt represented by MXn (M represents a metal cation having an oxidation number of n, X represents a monovalent anion including a substituted sulfonyl group represented by —S(═O)2—R3 (R3 represents a hydrocarbon group having 10 or less carbon atoms or a group in which some or all of hydrogen atoms in the hydrocarbon group are substituted with fluorine atoms), and n represents an integer of 1 to 4), a substituent bonded to a carbon atom in a carbonyl group of the N,N-disubstituted amide is R1, and two substituents bonded to nitrogen atoms in an amide group are both R2.
