To a solution of (E)-methyl 4-methyl-4-phenyl-2-pentenoate (0.3 g) in absolute methanol (10 ml) was added metallic magnesium ribbons (0.36 g) and the mixture was stirred at room temperature for 2 hours. To the reaction mixture was added 10% hydrochloric acid and then the mixture was extracted with ethyl acetate. The extract was washed with a saturated aqueous solution of sodium chloride, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to yield 0.30 g of [compound A].
