Reaction Steps

Thionyl chloride (Aldrich, 4.08 g, 2.5 ml, 34.3 mmol) was added dropwise to anhydrous MeOH (10mL) in ice-water-salt bath. After 20 min, 3-(4-aminophenyl)propionic acid (Trans World Chemicals, 1.7 g, 10.3 mmol) was added and the reaction mixture was allowed to stir at rt overnight. The resulting reaction mixture was concentrated in vacuo and the residue was diluted with EtOAc, washed with sat. aqueous NaHCO3, water, and brine. The organic layer was dried over Na2SO4 and concentrated in vacuo to give methyl 3-(4-aminophenyl)propanoate (1.80 g, 98%).
