In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 1882-71-9, name is 2-Amino-5-methoxybenzamide belongs to amides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. name: 2-Amino-5-methoxybenzamide
General procedure: A 12mL vial was charged with MCM-41-2P-Pd(OAc)2 (2molpercent), 2-aminobenzamide (1mmol), aryl iodide (1mmol) (if solid) and a stirring bar. Then, DMF (2mL), aryl iodide (1mmol) (if liquid) and DBU (2mmol) were injected by syringe under an argon atmosphere. The vial was placed in an alloy plate, which was transferred into a 300mL Parr Instruments 4560 series autoclave under an argon atmosphere. After flushing the autoclave three times with CO, a pressure of 10bar CO was fixed at ambient temperature. The autoclave was heated for 20hat 120¡ãC. After completion of the reaction, the autoclave was cooled to room temperature and the pressure was released carefully. The reaction mixture was diluted with ethyl acetate (10mL) and filtered. The palladium catalyst was washed with distilled water (2¡Á5mL) and acetone (2¡Á5mL), and reused in the next run. The filtrate was concentrated in vacuo and the pure product was isolated by either washed with water, ethyl acetate and finally hexane or recrystallization from MeOH.
The synthetic route of 1882-71-9 has been constantly updated, and we look forward to future research findings.
