Reaction Steps

A mixture of 3-(1,4-dioxa-spiro[4,5]dec-7-en-8-yl)-1H-indole (8.0 g, 31.3 mmol) and 10% palladium on carbon (1.3 g) in ethanol (700 ml) was hydrogenated for 18 hours. The catalyst was filtered off and the solvent removed under vacuum to afford 8.01 g (99%) of product as a white solid.
