New learning discoveries about 893566-75-1

As the paragraph descriping shows that 893566-75-1 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.893566-75-1,Tert-butyl 8-bromo-3,4-dihydroisoquinoline-2(1H)-carboxylate,as a common compound, the synthetic route is as follows.,893566-75-1

With N2 in dioxane (20 mL)8-bromo-3,4-dihydroisoquinoline-2(1H)-carboxylic acid tert-butyl ester(R-1) (1100 mg, 3.52 mmol), NaI (4.76 g, 31.8 mmol),CuI (402 mg, 2.12 mmol) and trans-N,N-dimethylcyclohexaneThe mixture of (602 mg, 4.22 mmol) was purified for 10 minutes.The resulting yellow suspension was stirred in a sealed tube at 110¡ã C. for 48 hours. The reaction was diluted with petroleum ether (50 mL) and filtered.The filtrate was concentrated in vacuo and the residue was purified by tannin chromatography for petroleum etherThe EtOAC in (from 0 to 20percent) was purified by stripping to provide R-2 (1200 mg, 94.8percent) as a pale yellow gum.
