2-cyclopropyl-2-hydroxyacetohydrazide

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: As described for example 112a, (rac.)-2-cyclopropyl-2-hydroxy-acetic acid methyl ester (Newall, Christopher Earle; Foxton, Michael Walter; Hartley, Charles David; Looker, Brian Edgar. Cephalosporin antibiotics. Eur. Pat. Appl. (1985), 57 pp) in methanol was reacted with hydrazine hydrate (1.0 equivalent) at rt for 76 h. All volatiles were evaporated and the residue was triturated with hexane to afford the title compound as a white solid (yield: 69%). MS: m/e=112.2 [M−H2O]+. All volatiles were evaporated the residue was triturated with hexane
