Abstract

NEW MATERIAL:A compound expressed by formula I (R1 is H or alkyl; R2 is alkyl). EXAMPLE:N,N-Dimethyl-2-cyano-5-methoxy-2,4-pentadienoamide. USE:A raw material for medicine or agricultural chemical. An intermediate for pyridinesulfoneamide based herbicide (especially herbicide for core field). PREPARATION:A cyanoacetamide expressed by formula II is reacted with a 1,1,3,3-tetramethoxypropane expressed by formula II in the presence of a catalyst and demethanol agent to provide the aimed compound expressed by formula I. As the catalyst and demethanol agent, paratoluene-sulfonic acid, etc. and acetic anhydride are used respectively. The above-mentioned reaction may be carried out by blending the catalyst and demethanol agent with the both raw materials or blending the catalyst and demethanol agent with either one of raw materials and then blending the blend with the residual raw material.
