YieldReaction ConditionsOperation in experiment
65% at 0℃; Reflux Intermediate 26: 2-Acetylhvdrazinecarbothioamide; To a solution of thiosemicarbazide (9.1 Og, O.I Omol) in anhydrous THF (100ml) was added acetyl chloride (8.64g, 0.11 mol) at O0C slowly. The mixture was heated to reflux for 3hs. After cooling, water (100 mL) was added and the mixture was extracted with ethyl acetate (3 x 10OmL). The organic phase was washed with brine, dried and concentrated under reduced pressure. Purification by column chromatography (MeOH/DCM=1/1 ) gave the title compound (8.64g, 65percent yield); mass spectrum (ESI) m/z calcd for C3H7N3OS 133.03, found 134.0 (MH+).

YieldReaction ConditionsOperation in experiment
60% for 2 h; Reflux A suspension of thiosemicarbazide 2 (5.0 g, 55 mmol) in glacial acetic acid (25 ml) was heated under reflux for 2 h to give a clear solution. The crude acetylthiosemicarbazide slowly crystallised from solution on cooling. It was recrystallised from ethanol to give the pure product. Yield (4.4 g, 60percent), m.p. 163-165 °C (lit.1 m.p. 166 °C).
