Procedimiento

7 g of 1H-1,2,4-triazole were dissolved in 65 g of a commercial 40% aqueous solution of tetrabutylammonium hydroxide. The mixture was evaporated in vacuo and 50 ml portions of toluene were added several times to remove the water obtained azeotropically. Finally the viscous product was dried in high vacuum until constant in weight. There was obtained 31.5 g of a yellowish, viscous mass.
