반응 단계

1N NaOH (100 μL) and H2O (500 μL) is added to a solution of (4Z)-2-(2-furyl)-4-[(5-phenyl-2-furyl)methylene]-1,3-oxazol-5(4H)-one (10 mg, 0.0327 mmol), prepared as described above, in acetone (1 mL). The reaction mixture is heated to 75° C. for one hour and then cooled to 25° C. The crude mixture is loaded onto a QAX column, which was pre-treated with MeOH. After 2 minutes the column is washed with MeOH and the product is eluted with 3% HCl/MeOH. Subsequently, the column is washed with MeOH (2 mL) and the combined washings are concentrated under reduced pressure to provide 9.5 mg of (2Z)-2-(2-furoylamino)-3-(5-phenyl-2-furyl)prop-2-enoic acid.
