摘要: Process for preparing 1,3-disubstituted urea of the formula:
wherein R 5 is the same as or different from R 6 , and each of R 5 and R 6 is independently linear or branched, alkyl of 1-20 carbon atoms, alkenyl group having 2 to 20 carbon atoms or alkynyl group having 2 to 20 carbon atoms, which may have phenoxy, alkoxy of 1-13 carbon atoms, monocycloalkyl of 3-8 carbon atoms, bicycloalkyl of 6-12 carbon atoms, aryl of 6-13 carbon atoms, furyl, pyridyl, or aralkyl of 7-20 carbon atoms, comprising reacting cyclic carbonic acid ester with an amine using alkali metal alkoxide or trialkylamine as base, in safety and high yield.-
