Reaction Conditions

Reaction Steps

To a 25 mL RB flask fitted with magnetic stirrer was charged with methanol (10 mL). To the stirred solvent was added 3-[4-(benzyloxy)-2-methoxyphenyl]-3-cyanopropanoic acid (0.62 g, 2.56 mmol) and methane sulfonic acid (1 mL), it was heated at 65° C. for 2 h. The RM was concentrated, extracted with ethyl acetate (50 mL×2). The organic layer was washed with water (50 mL) and saturated brine solution (50 mL). The organic layer was dried over anhydrous Na2SO4 and the solvent was removed under reduced pressure. The product was obtained as brown liquid. (0.65 g, yield: 100.0%).
