Versuchsvorschrift

A mixture of isopropyl 5-fluoro-3-methyl-1H-indole-2-propanoate (0.42 g),1N sodiumhydroxide (6.3 ml) and methanol (20 ml) are stirred at room temperature for 4 hours. The reaction mixture is poured into water, washed with methylene chloride, acidified with 1N HCl and extracted with methylene chloride. The organic layer, dried and evaporated, affords 0.36 g of 5-fluoro-3-methyl-1H-indole-2-propanoic acid.
