Participants

Reaction Steps

As described for example 112a, isoxazol-3-yl-acetic acid methyl ester in ethanol was reacted with hydrazine hydrate (2 equivalents) at rt for 16 h. After evaporation of the solvent the residue was chromatographed (SiO2, dichloromethane:methanol:aq.ammonia (25%)=100:0:0 to 90:10:1) to afford the title compound as a white solid (yield: 78%). MS: m/e=142.1 [M+H]+.
