Procedure

A mixture of 3-(2,4-pentanedion-3-yl)thio-1H-1,2,4-triazole (Example 46-a) (2 g), phenylhydrazine (1 ml) and ethanol (10 ml) was heated and stirred for 4 hours on an oil bath at 100° C. The reaction solution was concentrated under reduced pressure, and then the residue was crystallized from ethanol-ethyl acetate to yield the title compound (1.42 g).
