As the rapid development of chemical substances, we look forward to future research findings about 877861-62-6

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 organics were dried (Na2SO4) and evacuated. The crude carbamate was used directly in the next step.

As the rapid development of chemical substances, we look forward to future research findings about 877861-62-6
