Procedure
A mixture of 106.0 g (0.53 mole) of p-benzyloxyphenol (Eastman), 28.6 g (0.53 mole) sodium methoxide (MCB) and about 2 g of sodium iodide in 600 ml of dimethylformamide is stirred for 5 minutes, after which 73 g (0.53 mole) of 6-chlorohexan-1-ol (MCB) is added, and the mixture is refluxed with stirring. The methanol formed in the reaction is allowed to distill off. After 2 hours reflux, the mixture is diluted with ice and water, 500 ml of 10% potassium hydroxide is added, and the resultant precipitate collected and dried. The solid is combined with 1 liter of butanone, refluxed and filtered. The residue is cooled, whereupon the desired product crystallizes out. The solid product is stirred with 1 liter of acetone at room temperature, the mixture is filtered to separate additional insoluble byproduct, the acetone boiled off and replaced with methanol, and the methanolic solution cooled to crystallize out the desired product, m.p. 94°-97° C.
