Reaction Steps

1,2,3,4-Tetrahydro-9-acridinamine (4.0 g) was suspended in 400 ml of toluene to which morpholine (3.5 g) and o-tolualdehyde (3.0 g) were successively added. The reaction mixture was refluxed overnight and then an additional 1.5 g of aldehyde was added. Reflux was continued for an additional six (6) hours and then the reaction mixture was concentrated and purified by flash chromatography (CH2Cl2, then 20% EtOAc/CH2Cl2). Fractions containing the pure product were concentrated and recrystallized from benzene/pentane to give 3.32 g of analytically pure product, m.p. 160°-162° C.
