Hydrazine hydrate (1:1) → HCID 13059386, compound

Participants

Reaction Steps

In 20 ml of ethanol were dissolved 1.70 g (8.9 mmole) of S-methyl-N-acetyl-L-cysteine methylester and 6 ml of aqueous 80% hydrazine hydrate solution and the solution was heated at reflux for 2 hours. After the reaction solution was concentrated in vacuo, a small amount of water was added to the residue and then distilled off in vacuo and this procedure was repeated three times to give white crystals. The crystals were washed with small amount of ethanol and dried to give 0.99 g (58% yield) of S-methyl-N-acetyl-cysteinylhydrazine.
