실험 절차

To a solution of NaOH (1.6 g, 40.54 mmol) in H2O (30 ml) was added of 2-Hydroxyimino-6-methoxy-3-oxo-indan-5-carboxylic acid dimethylamide (2.8 g, 10.67 mmol). The mixture was heated at 50° C. Then p-Toluenesulfonyl chloride (5.7 g, 30 mmol) was added in portions to the mixture. The mixture was heated at 80° C. for 15 min. After cooling carefully to room temperature, the precipitate (a little) was removed from the mixture. Mother liquid was acidified by concentrated HCl to PH=3-4 and the precipitate was collected and dried to give product (2.5 g, 89.28%). LC-MS: m/e 261 (M−1).
