Reaction Steps

To a solution of 0.72 g of 3-(3,4-diethoxy-phenyl)-propionic acid in 10 mL THF were added 1.6 mL of DIPEA, 0.45 g of HOBt, 0.63 g of EDC and 10 mL of MeNH2 (2M in THF). The reaction mixture was heated in a closed vessel overnight at 70° C. Further additions of MeNH2 were done during the next 12 h. The mixture was then concentrated in vacuo, the residue was taken up in sat. aq. NaHCO3 and washed with EtOAc (2×). The organic layers were combined, washed with brine, dried over MgSO4 and concentrated in vacuo. Purification by CC with EtOAc yielded 0.16 g of 3-(3,4-diethoxy-phenyl)-N-methyl-propionamide as solid.
