1072-91-9, name is 1,3,5-Trimethylpyrazole, belongs to pyrazoles-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Application In Synthesis of 1,3,5-Trimethylpyrazole
General procedure: SOCl2 (5 mL) was added to a round-bottom flask, and then 1a-i(1.0 mmol) and a catalytic amount of DMF (0.1 mmol) were added. Themixture was heated to reflux for 4 h (reaction monitored by HPLC),then excess SOCl2 was evaporated under reduced pressure. The residuewas dispersed in H2O (200 mL) and extracted with AcOEt. The organicphase was separated, dried, and concentrated. It was then purified byflash column chromatography (eluent: ethyl acetate/petroleum ether,1 : 10 v/v) to afford 2a-i.
The synthetic route of 1072-91-9 has been constantly updated, and we look forward to future research findings.
