実験手順

To a solution of the 5-methanesulfonyl-1H-indole-2-carboxylic acid methyl ester (0.49 g) in THF (12 mL) and water (4 ml) was added LiOH (0.098 g). The reaction mixture was left to stir for 2 hours. Acetic acid was added and the product extracted with dichloromethane. The organic extracts were combined, dried with magnesium sulfate, filtered and the filtrate evaporated to give the title compound as a solid (0.110 g).
