Reaction Conditions

Reaction Steps

To 500 parts of methanol, 115 parts of para-nitrophenyl-o-carbethoxyphenylthio ether, 10 parts of activated carbon and 1 part of ferric chloride hexahydrate were added, and the mixture was stirred at a liquid temperature of 60 to 65° C. for 20 minutes. To this reaction liquid, a mixture of 68 parts of 80% hydrazine monohydrate and 100 parts of methanol were added dropwise over 1 hour while maintaining the liquid temperature at 65° C. or less, and reaction was further carried out at the same temperature for 3 hours. The mother liquid obtained by filtration of the reaction liquid was concentrated and the precipitated solid was washed with water and dried to obtain 95.4 parts of para-aminophenyl-o-carbethoxyphenylthio ether which is the title compound.
