Reaction Steps

A solution of 4.0 g. of 9-acetoxyxanthene and 2.0 g. of 4-aminomethylpyridine in 100 ml. of benzene is refluxed for 24 hours. The reaction mixture is stripped of solvent and the residue dissolved in ether. The ether solution is washed with cold 5% sodium carbonate and water and dried over potassium carbonate and chromatographed with alumina and eluting with ether/hexane. The eluate is extracted with ether/acetone and concentrated in vacuo to give 4-pyridylmethyl-9-xanthylamine having a m.p. of 83°-85° C.
