With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.82771-60-6,7-Chloro-1,2,3,4-tetrahydroisoquinoline,as a common compound, the synthetic route is as follows.,82771-60-6
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).
As the paragraph descriping shows that 82771-60-6 is playing an increasingly important role.
