실험 절차

30 mg (3R,9S)-9-(tert-butyldimethylsilyloxy)-7,7-dimethyl-4-(1-methylcyclopropyl)-3-(4-(trifluoromethyl)phenyl)-2′,3′,5′,6,6′,7,8,9-octahydro-3H-spiro[furo[3,4-c]quinoline-1,4′-pyran] are dissolved in 3 ml acetic acid and 1 ml acetic acid anhydride. 30 mg Platinum-(IV)-oxide are added and the mixture is hydrogenated for 2 hours at 60° C. and 3 bar. The catalyst is filtered off and washed with methanol. The liquid phases are combined and the solvents are evaporated in vacuo. The residue is chromatographed on silica gel (petrole ether/ethylacetate 100:0 to 90:10).
