With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.74420-05-6,N-Methyl-4-chloro-7-azaindole,as a common compound, the synthetic route is as follows.,74420-05-6
To a 100 mL reaction vial was added 4-chloro-1-methyl-1H-pyrrole [2,3-b]pyridine (2.29 g, 10 mmol).Sodium sulfide (1.17 g, 15 mmol), N-methylpyrrolidone (30 mL), Heat to 80 C and stir the reaction for 3 hours. Then, cesium carbonate (6.52 g, 20 mmol) was added to the reaction flask. And 2-bromocyclobutylacetate (2.15 g, 11 mmol), Continue to react at 100 C for 2 hours, After completion of the reaction, water (150 mL) was added, and the mixture was extracted three times with ethyl acetate (3¡Á100 ml). The organic layers are combined and washed with saturated brine. Dry with sodium sulfate and filter. After rotary distillation, the intermediate was obtained as an intermediate 50.3 (2.11 g), yield 60%.
The synthetic route of 74420-05-6 has been constantly updated, and we look forward to future research findings.
