Reaction Steps

10 g of 3-p-propylphenyl-4,5-dihydro-6H-pyran (obtainable by hydrolysis of 3-bromotetrahydropyran to give 3-hydroxytetrahydropyran, reaction with p-propylphenyl magnesium bromide to give 3-p-propylphenyl-3-hydroxy-tetrahydropyran followed by dehydration) are dissolved in 100 ml of ethanol and hydrogenated to standstill on 2 g of Raney nickel at 20° under 3 atmospheres. After decantation and evaporation, 3-p-propylphenyltetrahydropyran is obtained.
