Procedure
4-(Tetrahydro-2H-pyran-2-yloxy)phenol (19.0 g, 0.1 mol) and 4-(1-hydroxy-3-butenyl)benzonitrile (17.8 g, 0.1 mol) was mixed in toluene, and cooled to 0° C. (under nitrogen). TBP (22.9 g, 0.11 mol) was added, followed by ADDP. The mixture was stirred at rt overnight, filtered, and evaporated. Purification by chromatography on silica gave 24 g (68.7%) of the desired compound.
