Abstract
To provide a method for producing a (4,5-dihydroisoxazol-3-yl)thiocarboxamidine salt compound simply, safely and in good yield, whereby drawbacks of prior art have been solved. A method for producing a (4,5-dihydroisoxazol-3-yl)thiocarboxamidine salt compound of the formula (2): wherein each of Rand Rwhich are independent of each other, is a hydrogen atom, an alkyl group or a cycloalkyl group, each of Rand Rwhich are independent of each other, is a hydrogen atom or an alkyl group, provided that Rand R, or Rand R, may be bonded to each other to form a cycloalkyl group together with the carbon atoms to which they are bonded, and Xis a halogen or an anionic residue derived from an acid, which comprises reacting a 3-halogeno-4,5-dihydroisoxazole compound of the formula (1): wherein R, R, Rand Rare as defined above, and Xis a halogen, with thiourea in the presence of an acid.
