Procedure
By the method of Example 5, 0.50 g (1.95 mmol) of trans-3-(3-pyridylmethyl)-4,6-chromandiol and 400 mg (2.15 mmol) of 2-(bromomethyl)-6-methyl pyridine were converted to present title product, purified by flash chromatography on silica gel using ethyl acetate as eluant to yield purified title product, o.14 g (20%), m.p. 66°-68° C.
