Versuchsvorschrift

The procedure of Example 4 is followed using 4,6-diphenyl-2-pyridone (6.18 g) and 6-bromohexanonitrile (6.60 g) in place of 6-bromohexanoate, silver carbonate (6.89 g) and toluene (300 cc) and the reaction mixture is refluxed for 72 hours. The material formed is purified by chromatography under pressure on silica gel (30-60 mm; eluent: n-hexane-ethyl acetate 9.5-0.5) to obtain 6-[(4,6-diphenyl-2-pyridyl)oxy]hexanonitrile as a white solid which is used directly in subsequent reactions.
