5334-43-0, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 5334-43-0 as follows.
EXAMPLE 3 1-Phenyl-4-cyano-5-(dicyclohexylaminosulfonylureido)pyrazole STR108 4.4 ml (50 mmol) of chlorosulfonyl isocyanate were added to a solution of 9.2 g (50 mmol) of 1-phenyl-4-cyano-5-aminopyrazole in 100 ml of methylene chloride. Stirring was carried out for 30 minutes at about 20 C., after which a solution of 7.5 ml (60 mmol) of triethylamine and 10 ml (50 mmol) of dicyclohexylamine in 50 ml of methylene chloride was slowly added dropwise. After the end of the addition, stirring was continued for a further hour and hydrolysis was then carried out with 200 ml of water. The organic phase was separated off and was worked up in a conventional manner to give the product. Yield: 87%.
