실험 절차

A solution of glycine (200 g) and KOH (200 g) in water (1000 ml) at 0° C. was treated dropwise with a solution of m-nitrobenzoyl chloride (100 g) in acetonitrile (100 ml). The reaction was allowed to warm to room temperature and was stirred for 4 hours. 12N aqueous HCl was added until pH<2. The reaction was allowed to stand overnight at room temperature. The resulting solid was filtered and washed with water (2×250 ml) and dried in vacuo at 60° C. 100 g of m-nitrohippuric acid was isolated. MS, 1H-NMR and CHN analysis were consistent with the desired product.
