Procedure

To a 250 ml single neck round bottom flask equipped with a reflux condensor and an argon inlet is added 2.35 gm of the 3-pyridyl-1-naphthylcarbinol and 100 ml of anhydrous tetrahydrofuran. The system is cooled to 0° C. and after cooling 0.26 gm sodium hydride is added. The system is stirred for an additional 20 minutes and 1.1 ml of allyl bromide is added. The system is allowed to come to room temperature over 1/2-hour and is stirred there for an additional 2 hours. Afterwards, the system is heated at reflux for 17 hours. At this time, water is added to the system and the product extracted with methylene chloride. The methylene chloride is then washed with water and dried over sodium sulfate. The methylene chloride is removed by stripping to give the 3-pyridyl-1-naphthylcarbinol allylether.
