Procedure
Using the procedure described in Example 5, 2-bromomethylnaphthalene (0.234 g) was reacted with 4-(3-hydroxyphenyl)-4-methoxy-2,6-dimethyltetrahydropyran (0.2 g, less polar isomer) to give 4-methoxy-2,6-dimethyl-4-[3-(naphth-2-ylmethoxy)phenyl]tetrahydropyran (0.29 g, 92%), m.p. 105°-107° C.
