実験手順
A suspension of 8 g [6-methoxy-3-(2-oxo-1,2-dihydroindol-3-ylidene)indan-1-yl]-acetic acid in 60 ml of water was added to 0.9 g of sodium hydroxide in 10 ml of water. The mixture was stirred at room temperature for 30 minutes and filtered. The filtrate was frozen and lyophilized to give 8 g of [6-methoxy-3-(2-oxo-1,2-dihydroindol-3-ylidene)-indan-1-yl]-acetic acid sodium salt.
