Production process of N-substituted amide compounds

In a process for producing an unsaturated N-substituted amide compound by bringing a strongly basic substance, a starting amide compound and a halogen-substituted compound into simultaneous contact in an aprotic polar solvent to react them together, the improvement wherein the reaction system the starting amide compound is acrylamide or methacrylamide;

• the strongly basic substance is an alkali metal hydroxide;
• the halogen-substituted compound is an allyl halide alkyl polyhalide, aralkyl halide or allyl halide compound;
• the amount of the strongly basic substance is 0.5-1.5 moles per mole of replaceable hydrogen of the starting amide compound;
• the amount of aprotic polar solvent is 10-90% by weight of the whole weight of the reactants including the solvent per se;
• the amount of water present at the beginning of the reaction is 5% by weight or less of the reaction system;
• and the reaction is initiated while maintaining the basic substance in a suspended state.
