With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1287-16-7,Ferrocenylacetic acid,as a common compound, the synthetic route is as follows.,1287-16-7

General procedure: A mixture of ferrocene acetic acid (1 mmol), the required 3-substituted-4-amino-5-mercapto-1,2,4-triazole(1 mmol), and p-toluenesulfonic acid (0.1 mmol) in DMF(10 mL) was stirred until a homogeneous solution was obtained. The mixture was exposed to microwave irradiation for about 3 min at 350 W and then cooled and poured into crushed ice. The mixture was adjusted to pH 7 with potassium carbonate and potassium hydroxide and then kept overnight at room temperature. The crude product was filtered off, dried and recrystallized from 80% ethanol to afford the pure product (Scheme 1).

General procedure: To a clean and dry round bottom flask with a septum, 3-5mmol of the ferrocenylketone were added and approximately 20mL of dimethoxyethane (DME) were transferred with a positive nitrogen pressure; the mixture was stirred to obtain a reddish solution. 0.75equivalents of lithium aluminum hydride (1M in tetrahydrofuran) were added, and a change of color from red to yellow in the solution was observed. The reaction was stopped after 30min at room temperature; complete transformation was confirmed with TLC. After this time, Glauber’s salt was added and the mixture was stirred until a formation of a granular precipitate was observed. The mixture was filtered, and the solvent was eliminated to obtain yellow to orange oils or solids. The compounds were employed directly for following reactions without further purification.
