Methyl 1,2,3,4-tetrahydroisoquinoline-6-carboxylate hydrochloride, cas is 877861-62-6, it is a common heterocyclic compound, the tetrahydroisoquinoline compound, its synthesis route is as follows.
877861-62-6, A mixture of ammonium thiocyanate (0.105 g, 1.384 mmol), 6-methoxycarbonyl- 1,2,3,4-tetrahydroisoquinoline hydrochloride (0.3 g, 1.3176 mmol) and THF (2 mL) was heated in a CEM microwave reactor for 1 h at 100 0C. Upon cooling to room temperature, the reaction mixture was diluted with EtOAc, and washed with H2O, 1 N HCl, saturated aqueous NaHCO3 and brine respectively, dried over anhydrous MgSO4, and concentrated under reduced pressure to afford methyl 2- (aminocarbonothioyl)-l,2,3,4-tetrahydroisoquinoline-6-carboxylate (0.33 g, 47%) as a white solid. LCMS: (FA) ES+ 251.
As the rapid development of chemical substances, we look forward to future research findings about 877861-62-6
