A common heterocyclic compound, the tetrahydroisoquinoline compound, name is Methyl 1,2,3,4-tetrahydroisoquinoline-6-carboxylate hydrochloride,cas is 877861-62-6, mainly used in chemical industry, its synthesis route is as follows.
877861-62-6, Step 1 : Preparation of 2-(1 ,1-dimethylethyl) 6-methyl 3,4-dihvdro-2,6(1/-/)-isoquinoline- dicarboxylate; To a solution of methyl 1 ,2,3,4-tetrahydroisoquinoline-6-carboxylate hydrochloride(0.30 g, 1.32 mmol) in dioxane/H2O (2:1 , 5 ml.) was added 1 N NaOH (1.97 ml_, 1.97 mmol) followed by BoC2O (0.43 g, 1.97 mmol). The reaction was stirred at room temperature for 1 hour, at which time LCMS indicated complete conversion to product.The reaction was poured into H2O (10 ml.) and extracted with CH2CI2 (3×10 ml_). The
As the rapid development of chemical substances, we look forward to future research findings about 877861-62-6
