The present invention relates to a method for producing a compound of the formula:wherein R1 is an optionally substituted hydrocarbon group; R2 is H or an optionally substituted hydrocarbon group; and Q is an optionally substituted heterocyclic group, or a salt thereof which comprises subjecting a compound of the formula:wherein R1 has the same meaning as defined above, or a salt thereof to a nitration reaction (a), and further subjecting the resulting mixture without isolating/purifying the resulting compound of the formula:wherein R1 has the same meaning as defined above, or a salt thereof to a reaction (b) with a compound of the formula:wherein each symbol has the same meaning as defined above, or a salt thereof. According to the production method of the present invention, a compound [IV] as an intermediate of a guanidine derivative having an excellent insecticidal activity, or a salt thereof can be mass-produced, industrially. |
