Uses
Lopatol (CAS NO.19881-18-6) is taeniafuge new drugs. It Echinococcus granulosus adults and larvae were significant effects of insecticide rate was 92.6%. It have a good efficacy in nematodes and schistosomes .
Production
To pairs of nitro-chlorobenzene as raw materials in the presence of potassium hydroxide with the condensation of nitro-phenol 1 - (4 - nitrophenoxy) -4 - nitrobenzene, and then use iron reduced to 1 - (4 - aminophenoxy) -4 - nitrobenzene. Finally with the light oxygen or sulfur S 2 P 5 reaction obtained saltpeter Thiocyanate ether. Intermediate 1 - (4 - aminophenoxy) -4 - nitrobenzene may also be right nitrochlorobenzene condensation obtained with paracetamol.
