Reaction Steps

9-Amino-1,2,3,4-tetrahydroacridin-1-ol (5.36 g) was refluxed for 48 hours in 300 ml of toluene that contained 4-phenylpiperidine (8.06 g) and p-toluenesulfonic acid monohydrate (9.5 g). At the end of this time the reaction mixture was concentrated and the residue purified by flash chromatography (5% Et3N/toluene) to give, after concentration of theproduct-containing fractions and recrystallization from EtOAc/pentane, 3.22g of analytically pure product, m.p. 189°-190°.
