Reaction Steps

3-t-butyl-1-chlorocarbonyl-5-(methylthio)pyrazole (4.0 g) in ether (25 ml) was added dropwise with stirring to a solution of diethylamine (3.9 g, 5.5 ml) in ether (25 ml) at room temperature. The reaction mixture was refluxed for 1/2 hour and then filtered, and the ether layer washed with water, dried and evaporated to give crude product. Recrystallisation from petrol gave 1-(diethylcarbamoyl)-3-t-butyl-5-(methylthio)pyrazole, melting point 55°-6°. Yield 54%.
