Procedure
A 10.0 g portion of 5-chloro-2-nitroaniline, 8.0 g of 1,2,4-triazole and 16.0 g of potassium carbonate were suspended in 50 ml of DMF and stirred for 5hours while heating at 130° C. The reaction solution was poured into ice water, and the thus precipitated crystals were collected by filtration and washed with purified water. By washing the crystals with methanol, 10.0 g (84% in yield) of the title compound was obtained. Its physical property values are shown below.
