Versuchsvorschrift
To a solution of 1.09 g of 5-(4-aminophenyl)-3-(2-pyridyl)-1,2,4-oxadiazole in 200 ml of dry tetrahydrofuran containing 0.42 g of triethylamine, 0.50 g of thiophosgene is added and the mixture stirred at room temperature for 6 hours. After filtration, the solution is evaporated in vacuo to give the crude product. It is crystallized from petroleum ether to give 0.65 g (54%) of the title product, m.p. 145°-146° .
