실험 절차
1-(2-Amino-3,4,5,6-tetrafluorophenyl)-3-(2,6-dichlorophenyl)thiourea was obtained by boiling a mixture of 1 g of 1,2-diamino-3,4,5,6-tetrafluorobenzene with 1.13 g of 2,6-dichlorophenyl isothiocyanate in 30 ml of anhydrous THF for 4 hours. After distilling off the solvent, the thiourea was brought to crystallization under diisopropyl ether and 1.88 g of 1-(2-amino-3,4,5,6-tetrafluorophenyl)-3-(2,6-dichloro-phenyl)thiourea were obtained as a crystalline solid. M.p.: >300° C.
