6-Methoxy-1,2,3,4-tetrahydroisoquinoline, cas is 42923-77-3, it is a common heterocyclic compound, the tetrahydroisoquinoline compound, its synthesis route is as follows.
EXAMPLE 42D 1,2,3,4-tetrahydro-6-isoquinolinol A solution of boron tribromide (1.2 mL, 12.5 mmol) in dichloromethane (12.5 mL) was added dropwise to a -78 C. solution of 6-methoxytetrahydroisoquinoline (1.0 g, 5.0 mol, prepared as described in Org. Synth 1988, 67, 60) in dichloromethane (38 mL) The mixture was stirred for 1 hour, warmed to 0 C., stirred for 1 hour, warmed to room temperature, and stirred for 1 hour. The mixture was cooled to -78 C., treated dropwise with methanol (20 mL), warmed to room temperature, stirred for 1 hour, and concentrated to provide the desired product. MS (DCI/NH3) m/e 150 (M+H)+.
With the rapid development of chemical substances, we look forward to future research findings about 42923-77-3
