Reaction Steps

A mixture of 5.16 g. 3-ethylthio-1,2,4-triazole, 7.8 g. N-n-butyl-N-propylcarbamoyl chloride, 35 ml. dry tetrahydrofuran and 8 ml. dry triethylamine was refluxed under anhydrous conditions for 24 hours. The reaction mixture was worked up as described in Example 1 to give a residual oil. This oil was distilled under reduced pressure to give 1-(N-n-butyl-N-propylcarbamoyl)-3-ethylthio-1,2,4-triazole, b.p. 127° C./0.2 mm. (91.2% 1-isomer by GLC assay). Elemental analysis satisfactory.
