実験手順
Dissolve 27.0 g of ethyl indole-2-carboxylate in 250 ml of trifluoroacetic acid. Add 2.05 g of platinium oxide, hydrogenate the mixture at 50 lb/in2 at room temperature. Filter the mixture and concentrate the filtrate in vacuo to give a residue. Suspend the residue in ether and treat with cold dilute sodium hydroxide solution. Dry the organic layer over magnesium sulfate and concentrate it to give ethyl octahydroindole-2-carboxylate, a pale yellow oil.
