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

Participants

Reaction Steps

To a suspension of 2-(4-methoxyphenyl)hydrazinecarboxamide (1.81 g, 9.99 mmol) in 20 mL of toluene, pyridine (1.01 mL, 12.5 mmol) and then a solution of 4-methoxybenzoyl chloride (2.13 g, 12.5 mmol) in 10 mL of toluene were added. The mixture was refluxed with stirring for 1 hour. After cooling, 500 mL of ethyl acetate-tetrahydrofuran (9:1) and 100 mL of water were added to the mixture. After vigorous shaking, an insoluble material was isolated by filtration and dired in vacuo to give 2-(4-methoxybenzoyl)-2-(4-methoxyphenyl)hydrazinecarboxamide (1.95 g, 61.9% yield).
