Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 92028-21-2, name is 6-Methoxy-[1,1′-biphenyl]-3-amine hydrochloride, A new synthetic method of this compound is introduced below., COA of Formula: C13H14ClNO
Under nitrogen, compound X (from Example 38 part a) (5.0 g, 16.7 mmol) was mixed with toluene (80 mL) and 4-methoxy-3-phenylaniline hydrochloride (4.3 g, 18.3 mmol) was added to form a slurry. 2,2′-Bis(diphenylphosphino)-1,1′-binaphthyl (1.6 g, 2.5 mmol) was added, followed by tris(dibenzylideneacetone)dipalladium(0) (760 mg, 0.83 mmol) and finally sodium tert-butoxide (5.3 g, 55 mmol). The mixture was heated at 90 C. for 150 min and then cooled to room temperature. Water (150 mL) was added followed by ethyl acetate (150 mL) and the phases partitioned. The aqueous layer was extracted with ethyl acetate (150 mL) and the combined organics washed three times with 0.5 M sodium bisulfate (200 mL), once with saturated sodium bicarbonate (150 mL) and twice with saturated sodium chloride (150 mL). The organics were dried over magnesium sulfate (50 g) and the volatiles removed under vacuum to give N-tert-butoxycarbonyl-2-[4-(3-[phenyl-4-methoxyphenyl)aminophenyl]ethylamine (LL) (8.4 g) which was used without further purification.
The synthetic route of 92028-21-2 has been constantly updated, and we look forward to future research findings.
