Procedure
3-[3,4-Bis-(2-methoxy-ethoxy)-phenyl]-propionic acid (2 g×5) was dissolved in methanesulfonic acid (10 ml×5) in microwave process vial (20 ml×5), and the mixture was heated at 100° C. for 10 minutes under microwave irradiation. The reaction mixture was poured into ice (250 g), neutralized by 2M NaOH to PH 8-9, and then extracted by EtOAc/isopropyl alcohol. The organic layer was concentrated to give product (2.68 g, 28.3%). LC-MS: m/e 281 (MH+)
