Related Products of 67-51-6, These common heterocyclic compound, 67-51-6, name is 3,5-Dimethyl-1H-pyrazole, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: To an 8 mL dram vial was added iodobenzene diacetate (0.6 mmol, 1.5 equiv), and heteroarene(0.4 mmol, 1 eq.), anhydrous dichloroethane (1 mL), then chloride source (5 equiv). The solutionwas allowed to stir (1000 rpm) at 50 C for the indicated amount of time. After which the solutionwas washed with saturated sodium bicarbonate, followed by saturated sodium thiosulfate andconcentrated. The crude mixture was then purified by column chromatography.
Statistics shows that 3,5-Dimethyl-1H-pyrazole is playing an increasingly important role. we look forward to future research findings about 67-51-6.
