Procedure
4 Grams of 2-amino-3-(2-quinolon-4-yl)propionic acid hydrochloride was suspended in 50 ml of methanol. Under an ice-cooled condition with strring, 5.3 g of thionyl chloride was added dropwise thereto, the reaction mixture was stirred at a room temperature overnight. Methanol and thionyl chloride were removed by distillation under a reduced pressure, then the residue obtained was recrystallized from methanolacetone to obtain 2.4 g of methyl 2-amino-3-(2-quinolon-4-yl)propionate in the form of white powdery product.
