Procedure

12.6 parts of 3-phenyl-5-phenylthiopyrazole, 100 parts of toluene and 6 parts of phenyl isocyanate are stirred for 12 hours at 20° C. After the toluene has been distilled off, there is obtained 13 parts (70% of theory) of 1-(phenylcarbamoyl)-3-phenyl-5-phenylthiopyrazole; m.p.: 138° to 139.5° C (recrystallized from acetonitrile).
