The tetrahydroisoquinoline compound, cas is 82771-60-6 name is 7-Chloro-1,2,3,4-tetrahydroisoquinoline, mainly used in chemical industry, its synthesis route is as follows.
Example 32: 7-Chloro-3,4-dihydroisoquinoline Int-50 [00379] To a solution of 7-chloro-l ,2,3,4-tetrahydro-isoquinoline ( 1.15 g, 6.86 mmol) in DCM (70.0 mL, 1090 mmol) was added Mn02 (5.96 g, 68.6 mmol) at rt, and the mixture was stirred for 16h. The reaction was filtered through a Celite pad and the residual solid was rinsed with DCM several times. The filtrate was concentrated in vacuo and the residue was purified by ISCO silica gel column chromatography (40g, eluting with 50% EtOAc in DCM, 50mL/min flow) to give 915 mg of the title compound as colorless solid. NMR (400 MHz, DMSO-d6) delta 8.35 (t, J = 2.1 Hz, 1H), 7.52 (d, J = 2.2 Hz, 1H), 7.46 (dd, J = 8.0, 2.3 Hz, 1H), 7.28 (d, J = 8.0 Hz, 1H), 3.70 – 3.63 (m, 2H), 2.71 – 2.65 (m, 2H)., 82771-60-6
As the rapid development of chemical substances, we look forward to future research findings about 82771-60-6
