Benzaldehyde → HCID 9860677, compound

Participants

Reaction Steps

1,2,3,4-Tetrahydro-9-acridinamine (4.0 g) was dissolved in 400 ml of warm toluene and then morpholine (3.5 g) and benzaldehyde1 (2.65 g) were added and the reaction mixture was brought to reflux with a Dean-Stark water separator. After the solution was refluxed overnight an additional 2.65 g of benzaldehyde was added and reflux was continued an additional five (5) hours. At the end of this time the volatiles were removed under reduced pressure and the residue was purified by flash chromatography (EtOAc) to give 3.18 g of pure porduct after trituration with Et2O. Analytically pure material was obtained by recrystallization from cyclohexane, m.p. 168°-169° C.
