Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for industrially advantageously producing a urea derivative expressed by formula (2) (wherein R and R represent each independently a lower alkyl group). SOLUTION: The method for producing the urea derivative expressed by formula (2) comprises reacting an acid such as hydrochloric acid with a compound expressed by formula (1) (wherein, R and R represent each independently the same as stated above; R represents a lower alkyl group or a phenyl group which may be substituted).
