3-Hydroxy-3--1H-indol-2-ones (1, 12) have been reduced with NaBH4/MeOH/t-BuOH.After acidic treatment, 2- and 3-substituted indoles (2, 11 and 13, 14, respectively) were obtained.The intermediates 3 and 4 of the rearrangenment were isolated and the effect of the pyridylmethyl groups on the rearrangenment has also been established.
