With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.5264-35-7,5-Methoxy-3,4-dihydro-2H-pyrrole,as a common compound, the synthetic route is as follows.
5264-35-7, General procedure: A suspension containing 2,5-dimethyl-1H-pyrrole-3-carbohydrazide (2) (150 mg, 0.979 mmol,1.0 equiv.) and the appropriate methyl lactim (1.96 mmol, 2.0 equiv.) in toluene (2.00 mL, 0.5M) was heated in the microwave reactor at 180 ¡ãC for 1.0 h. The reaction mixture was allowedto cool to room temperature and was then concentrated under diminished pressure. The obtained15residue was applied to a silica gel column (50 g); eluting with 95:5 ? 75:25 DCM-MeOH(containing 10percent NH4OH) afforded the expected triazole.
As the paragraph descriping shows that 5264-35-7 is playing an increasingly important role.
