Reaction Steps

The 3-(3,5-Dimethoxy-phenyl)-propionic acid (2 g×5) was dissolved in methanesulfonic acid (10 ml×5) in microwave process vial (20 ml×5), the mixture was heated at 90° C. for 10 minutes under microwave irradiation. The mixture was poured into ice (250 g), neutralized by 2M NaOH to PH 8-9, and extracted by EtOAc. The organic layer was concentrated to give the product (8.8 g, 96.2%). LC-MS: m/e 193 (MH+)
