With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.57060-88-5,Methyl 1,2,3,4-tetrahydroisoquinoline-3-carboxylate hydrochloride,as a common compound, the synthetic route is as follows.,57060-88-5
Step A: Preparation of Methyl 1,2,3,4,4a,5,6,7,8,8a-Decahydroisoquinoline-3-carboxylate Methyl 1,2,3,4-tetrahydroisoquinoline-3-carboxylate hydrochloride (2.3 g, 10 mmol) in 200 ml absolute ethanol is hydrogenated at 50 psi, room temperature, using 0.6 g 5% Rh/C catalyst. After the theoretical amount of hydrogen is taken up (36 hours), the catalyst is filtered and the filtrate is evaporated to dryness. The residue is dissolved in methylene chloride and washed with a saturated solution of sodium carbonate. The organic phase is dried (Na2 SO4) and acidified with ethanolic HCl. Evaporation of the solvent yields 2.0 g of the product as a diastereomeric mixture which is used without further separation.
57060-88-5 Methyl 1,2,3,4-tetrahydroisoquinoline-3-carboxylate hydrochloride 12248067, atetrahydroisoquinoline compound, is more and more widely used in various fields.
