Procedure
Thionyl chloride (30 ml) was added at 0°-5° C. to a stirred solution of 3-methylamino-3-phenylpropionic acid (39 g) in anhydrous methanol and the mixture stirred at ambient temperature for 5 hours. The solution was evaporated under reduced pressure and the residue treated with 2N sodium carbonate (350 ml). The solution was extracted with dichloromethane (2×100 ml). The combined extracts were washed with water (250 ml) dried over magnesium sulphate and evaporated under reduced pressure to give methyl-3-methylamino-3-phenylpropionate (36.9 g) as a clear orange oil.
