実験手順

A mixture of 430 mg. of the product from Example 3 Part D, 2.0 gm. of 5% Pd/C, and 20 mL of carbitol was heated to reflux and refluxed for 21 hours, cooled, and filtered. The filtrate was diluted with water, acidified with hydrochloric acid, and extracted well with ethyl acetate. The organic phase was washed with brine, dried over sodium sulfate and evaporated in vacuo. The residue was triturated with dichloromethane and filtered to remove solid tetrahydrocarbazole. The filtrate was evaporated in vacuo to give the title product, 125 mg, 31%.
