Procedure
A solution of 4-cyano-5-(4-methyl-2-oxo-azetidin-1-yl)-1-(2,3,4-trichlorophenyl)pyrazole (1.0 g; prepared as described in Example 32) in di-n-butylamine (20 ml) was heated under reflux for 31/2 hours. The reaction mixture was evaporated to dryness and the residue chromatographed using dichloromethane-ethyl acetate (40:1) as eluent. Evaporation of the eluate containing the major component gave 4-cyano-5-[2-di-(n-butyl)aminocarbonyl-1-methylethyl]amino-1-(2,3,4-trichlorophenyl)pyrazole (0.95 g), m.p. 101°-103° C., in the form of a colourless solid.
