Versuchsvorschrift

A mixture comprising benzyl 2-(3,5-dimethyl-1H-1,2,4-triazol-1-yl)-3-oxobutanoate (step 2) (7.1 g, 24.71 mmol) and hydrazine (2.327 ml, 74.1 mmol) in EtOH (124 ml) were stirred at 50° C. for 3 hours. The reaction was allowed to cool to RT overnight. The resultant solid was then collected by filtration and washed with a small amount of cold EtOH to afford the title compound as a pale yellow solid; LC-MS Rt 0.61 mins; MS m/z 193.9 [M+H]+; Method=Method LowpH_v001.
