实验步骤: As described for example 112a, (formyl-methyl-amino)-acetic acid ethyl ester (Hay, Michael P.; Wilson, William R.; Denny, William A. Tetrahedron (2000), 56(4), 645-657) in ethanol was reacted with hydrazine hydrate (1.2 equivalents) at rt for 96 h. The mixture was concentrated and chromatographed (SiO2, dichloromethane:methanol:aq.ammonia (25%)=100:0:0 to 50:10:1) to afford the title compound as a colorless oil (yield: 84%). MS: m/e=100.1 [M+H−N2H4]+. The mixture was concentrated chromatographed (SiO2, dichloromethane:methanol:aq.ammonia (25%)=100:0:0 to 50:10:1)
