With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.42923-79-5,7-Nitro-1,2,3,4-tetrahydroisoquinoline,as a common compound, the synthetic route is as follows.,42923-79-5
The mixture of 7-Nitro- 1,2,3, 4-tetrahydro-isoquinoline (1.5 g, 8.38 mmole) and 10% Pd/C (300 mg) in diethyleneglycol (5 mL) was submitted to Smith Synthesizer under microwave radiation at 220 C for 25 min. The resulting mixture was diluted with MeOH arid filtered. The filtrate was concentrated and diluted with CH2Cl2, washed with sat’a’q. ‘ NH4CI and dried over Na2SO4. After filtration and concentration, the desired compound was isolated through flash chromatography (eluted with CH2Cl2:Me0H 9: 1) as an orange solid. MS: (ES+) 145(M+H). Calc’d. for C9H8N2 – 144.07.
As the paragraph descriping shows that 42923-79-5 is playing an increasingly important role.
