الإجراء التجريبي

A solution of α-methyl cinnamic acid (10.0 g., 61.7 mmol.) in dry methanol (250 ml.) was treated with 10% palladium on carbon and hydrogenated (balloon used) at room temperature for 16 hours. The reaction mixture was diluted with methanol (250 ml.), filtered through a Celite pad in a millipore unit, washing the pad well with methanol (2×100 ml.). The clear filtrate was evaporated to dryness to give 10.225 g. of title product as a thick syrup.
