Pyridine → 2-(4-Methoxybenzoyl)-2-(4-methoxyphenyl)hydrazinecarbothioamide

Participants

Reaction Steps

A mixture of 2-(4-methoxyphenyl)hydrazinecarbothioamide (0.5 g, 2.53 mmol), 4-methoxybenzoyl chloride (541 mg, 3.17 mmol), and pyridine (0.256 mL, 3.17 mmol) intoluene (10 mL) was refluxed for 1 hour. After cooling, the solvent was removed under reduced pressure. diisopropyl ether and small amount of methanol was added to the residue and a generated precipitate was isolated by filtration, washed with methanol-diisopropyl ether, and dried in vacuo to give 2-(4-methoxybenzoyl)-2-(4-methoxyphenyl)hydrazinecarbothioamide (277 mg, 33% yield).
