Procedure

A suspension of 3.3 grams (0.084 mole) of sodium hydride (60% in mineral oil) in 20 mL of toluene is stirred, and a solution of 24.3 grams (0.080 mole) of [(1,4-dioxaspiro[4.5]decan-8-yl)(3-trifluoromethylphenyl)]methanol in 65 mL of toluene is added dropwise. Upon completion of addition, the reaction mixture is stirred at ambient temperature for about one hour. After this time a solution of 13.7 grams (0.080 mole) of phenylmethyl bromide in 45 mL of toluene is added dropwise. Upon completion of addition, the reaction mixture is heated to reflux where it is stirred for about 4 hours. The reaction mixture is then cooled and shaken with water. The organic layer is separated and dried with magnesium sulfate. The mixture is filtered and the filtrate is concentrated under reduced pressure, yielding phenylmethyl [(1,4-dioxaspiro[4.5]decan-8-yl)(3-trifluoromethylphenyl)]methyl ether.
