Versuchsvorschrift

Methyl 1-methyl-1H-indole-6-carboxylate 166 (1.24 mmol) was stirred with sodium hydroxide (0.59 g, 14.88 mmol) in a 2:2:1 mixture of methanol/THF/water (7.5 mL) for 36 hrs at rt to form a precipitate which was collected by filtration and lyophilized overnight to give the title compound 167 (0.54 g, 99% yield). MS: 175.06 (calc), 176.1 (obs).
