Ethyl {[N′-(3-chlorophenyl)-N-(2,4-dichlorobenzoyl) carbamimidoyl]sulfanyl}acetate as an eco-friendly insecticidal agent against Spodoptera littoralis (Boisd.)

A method of making a ethyl {[N′-(3-chlorophenyl)-N-(2,4-dichlorobenzoyl)carbamimidoyl]sulfanyl}acetate compound, the method comprising:

• adding an Ar—CO—Cl dropwise while stirring to an equimolar amount of NH4SCN in dry CH3COCH3 and refluxing to obtain a first crude product;
• adding a solution of 3-chloroaniline in dry CH3COCH3 to obtain a reaction solution;
• refluxing the reaction solution;
• precipitating a second crude product from the reaction solution;
• filtering and purifying the second crude product via crystallization from an ethanol/dichloromethane 1:1 mixture;
• heating a mixture of the second crude product, ethoxycarbonylmethyl bromide and triethanolamine (TEA) in ethyl alcohol;
• vaporizing solvent;
• and
• crystallizing the ethyl {[N′-(3-chlorophenyl)-N-(2,4-dichlorobenzoyl)carbamimidoyl]sulfanyl}acetate compound from ethyl alcohol.
