    摘要: PROBLEM TO BE SOLVED: To directly obtain the subject compound useful as e.g. an infiltrative insecticide by reaction of a specific compound with an inexpensive and industrially readily available nitroguanidine in the presence of an alkali metal salt. SOLUTION: This new compound, (D) a cyclic nitroguanidine derivative of formula III, is obtained by reaction of (A) a compound of formula I [(n) is an integer of 2 of 3; A is a group of formula II (Q is a (substituted) aromatic ring or (substituted) heterocycle, pref. tetrahydro-3-furanyl; R and R are each H or a 1-4C alkyl)] with (B) nitroguanidine in the presence of (C) an alkali metal salt. For example, the reaction is carried out using N-(tetrahydro-3- furanylmethyl)propane-1,3-diamine as the component A and potassium chloride as the component C. The molar ratio B/A is pref. (1:1) to (10:1).
