Reaction Steps

1.60 g (3.66 mmol) of N-[2-(4-benzyloxy-3-methoxyphenyl)ethyl]-3-hydroxy-2-(4-chlorophenyl)acrylamide, 925 mg (5.49 mmol) of 48% hydrobromic acid and 15 ml of acetic acid were mixed and stirred at 80° C. for 1.5 hours. Water was added to the reaction mixture, which was followed by extracted with ethyl acetate twice, washed with saturated brine twice, dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure. The residue was subjected to silica gel column chromatography (eluent, hexane:ethyl acetate=2:1) to give 600 mg of 2-(4-chlorophenyl)-3-hydroxy-N-[2-(4-hydroxy-3-methoxyphenyl)ethyl]acrylamide.
