use

The product of chicken cecal coccidiosis and stack-shaped Eimeria, Eimeria tenella, Eimeria poison, Bordetella Eimeria have a good preventive effect. With high efficiency, low toxicity, stable performance, the advantages of small resistance. It can be used with coccidia ester combination better. Note: ① laying hens disabled; ② discontinued four days before slaughter; when the temperature is above 45 ℃ ③ disabled.

Anti coccidiosis drugs for the treatment of coccidiosis

Production method

1 is composed of 4,4'-nitro stilbene urea (DNC) and acetyl acetone and urea cyclization compound.

(1) DNC synthesis. Methyl amine and nitrobenzene by paranitroaniline reflux in dimethyl formamide (DMF) in the condensation, yield 85% -90%; p-nitroaniline and also by the reaction of phosgene in toluene and too, yield 96.5%; or nitrobenzene hydrochloride, in dibutyl phthalate with urea condensation heating is made.

50g nitroaniline was added 180mL of concentrated hydrochloric acid, warmed to dissolve with stirring, and reacted at reflux micro 1.5h. After cooling, the precipitated bright yellow leaf-shaped p-nitroanilide hydrochloride crystals, m.p. 173-174 ℃, 95% yield.

The hydrochloride 10.2g (0.0584mol) and 1.5g (0.025mol) of urea was added 60mL dibutyl phthalate, the reaction was stirred at 180 ℃ in 6h. Cooling to 20 ℃ filtered, washed with ethanol, water, washed with a small amount of toluene and dried to give a yellow green powder DNC, m.p. 310-314 ℃ (decomposition), yield 65%.

(2) Synthesis of nicarbazin. The 8.1g (0.027mol) DNC, 2.5g (0.042mol) urea, 4mL acetylacetone and a small amount of concentrated hydrochloric acid were added 35mL of anhydrous ethanol, the reaction mixture was stirred at reflux for 10-15h, cooled to room temperature and crystallized, isolated by centrifugation, ethanol washed, and dried to give a yellow composite powder, yield 80%

2 consists of 4,4 urea nitro stilbene (DNC) and 2-hydroxy-4,6-dimethyl-pyrimidine (HDP) at a molar ratio of 1: 1 complex. HDP prepared from acetylacetone and urea condensation reaction
