실험 절차

A solution of 4.8 g of the resulting 2-chloro-4-fluoro-5-isothiocyanatothiobenzoic acid (methoxycarbonylmethyl) ester in 50 ml of toluene is added dropwise, with stirring, at from 20° to 250° C. to a solution of 1.4 g of hexahydropyridazine in 20 ml of toluene. The batch is then stirred for a further 8 hours at room temperature and is then concentrated by evaporation in vacuo to yield 4.4 g of 2-chloro-4-fluoro-5-(1-hexahydropyridazinylthiocarbonylamino)-thiobenzoic acid (methoxycarbonylmethyl) ester in resinous form.
