1.9 g (9.8 mmol) [1,2,4]-triazol-1-ylacetic acid ethyl ester [Ainsworth et al., J. Am. Chem. Soc. 1955, 77, 621-623] and 3.6 ml (2.9 g, 19.6 mmol) dimethylformamide diethyl acetal are stirred at a bath temperature of 100° C. for 12 h. For working up, the cooled reaction solution is concentrated on a rotary evaporator and the residue is dried in vacuo.
