HCID 91693Penconazole

Procedure

6.2 g of the 1-[2-(2,4-dichlorophenyl)-pentyl-1,2-diformylhydrazine obtained according to Example 14 are heated, without purification, in 50 ml of formamide at 170° C. for 6 hours. Chromatography of the product obtained yields 1-[2-(2,4-dichlorophenyl)-pentyl]-1H-1,2,4-triazole, the 1H-NMR spectrum of which agrees with the 1H-NMR spectrum of the same compound described in Example 12.
