With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.185613-91-6,4-(Benzo[d][1,3]dioxol-5-yl)thiazol-2-amine,as a common compound, the synthetic route is as follows.
4-(Benzo[d] [1,3]dioxol-5-yl)thiazol-2-amine(2) (1.00 g, 4.54 mmol) and NaH (0.164 g, 6.82 mmol) to THF (15 ml) todissolved and then allowed to react at room temperature for 1 hour under a nitrogen stream. Then slowly added dropwise atroom temperature 3a(trifluoromethyl) benzyl bromide (1.63 g, 6.82 mmol) and allowed to react for 10 minutes. After thereaction was finished, it was concentrated under reduced pressure and extracted three times into a saturated solution ofNaHCO3 is dissolved in ethyl acetate. The ethyl acetate layer was separated and dried with anhydrous Na2SO4, then purifiedby column chromatography (Ethyl acetate: Hexane = 1: 5) to give the compound 1c to give. Yield 17.2%
185613-91-6, The synthetic route of 185613-91-6 has been constantly updated, and we look forward to future research findings.
