Reaction Steps
1,8-Octanediol (16.8 g) (115 mmol) and 4.83 g of dihydropyran (57.5 mmol) in 1400 ml of dichloromethane containing 5 drops of concentrated HCl were stirred for 2 hours. Then 10 g of NaHCO3 were stirred in and the solution was filtered. Dichloromethane was removed with a rotary evaporator, and the resulting residue was triturated with pentane; the undissolved solid was 1,8-octanediol. The solid was filtered from the pentane solution, and the pentane was removed with a rotary evaporator to give 13.2 g (99.8%) of crude product oil.
