1-Phenethylamine, (+)- → HCID 60123694, compound

Participants

Reaction Steps

To a stirred solution of 6,7-dihydro-5H-quinolin-8-one (3.02 g, 20.5 mmol) in dry MeOH (100 mL) was added (R)-(+)-α-methylbenzylamine (2.61 mL, 20.5 mmol) via syringe. The resulting mixture was stirred 24 h, at which point additional (R)-(+)-α-methylbenzylamine (0.26 mL, 2.0 mmol) was added and the reaction was stirred for an additional 24 h. The solvent was removed in vacuo and dried for 3 days at room temperature under reduced pressure (0.1 Torr) to afford 5.38 g (95%) of the title compound as a red/brown solid.
