HCID 635800953-[(2-Furanylmethyl)thio]propanoic acid, hydrazide

Procedure

To a stirring 10 mL EtOH solution of 4.29 g (20 mmol) of ethyl 3-(furylthio)propanoate was added 0.71 g (22 mmol) of hydrazine hydrate. After heating at reflux for 24 hours, the reaction was stirred for 24 hours at room temperature. The solvent was then removed under vacuum, and the residue was dissolved in EtOH and filtered through a bed of charcoal. 2.77 g (69%) of product, which was a water white viscous liquid, was recovered and was employed immediately in the manner described in Example 13, below.
