6-(Trifluoromethyl)-1,2,3,4-tetrahydroisoquinoline hydrochloride, cas is 215798-14-4, it is a common heterocyclic compound, the tetrahydroisoquinoline compound, its synthesis route is as follows.
Example 20; 1 -phenyl -S-U-re-ftrifluoromethvD-S^-dihvdro-?d ffl-isoalphauinolinvnbutvD-IH-indole-S- carboxylic acid; To a solution of methyl 3-{4-[(methylsulfonyl)oxy]butyl}-1 -phenyl-1 H-indole-5-carboxylate (Intermediate 93) (120 mg, 0.3 mmol) in MIBK (10 ml), was added K2CO3 (105 mg, 0.75 mmol) and 6-(trifluoromethyl)-1 ,2,3,4-tetrahydroisoquinoline hydrochloride (72 mg, 0.36 mmol). The reaction mixture was stirred at 12O0C for 2 days. The mixture was filtered and the filtrate was evaporated. The residue was purified on SiO2 eluting with dichloromethane to dichloromethane/ethyl acetate 95/5 to give the ester (15 mg). The ester was diluted with methanol, NaOH 1 N (3 ml) was added and the mixture was stirred at reflux for 24 hours. The mixture was cooled and HCI 1 N ( 3 ml) was added. The mixture was concentrated and, the residue was purified on SiO2 eluting with dichloromethane to dichloromethane/ethyl acetate 95/5. The product was triturating in cyclohexane and the solid obtained was filtered and washed with pentane to give after drying the title compound as a cream solid (9 mg, 6%).MR1H (300 MHz), CDCI3 delta: 8.36 (s, 1 H), 7.83 (d, 1 H, J=9.63 Hz), 7.41 (m, 5H), 7.29 (m, 3H), 7.1 1 (s, 1 H), 7.06 (d, 1 H, J=8.61 Hz), 3.79 (m, 2H), 2.96 (m, 2H), 2.90 (m, 2H), 2.82 (m, 2H), 2.68 (m, 2H), 1.78 (m, 4H). TOF MS ES+ exact mass calculated for C29H27F3N2O2: 493.2103 (M+H)+ Found: 493.2105 (M+H)+ ; RT= 2.97 min.
215798-14-4, With the rapid development of chemical substances, we look forward to future research findings about 6-(Trifluoromethyl)-1,2,3,4-tetrahydroisoquinoline hydrochloride
