실험 절차

A 4:1 mixture of geometrical isomers, containing predominantly 2,2,2-trifluoro-.N.-(2-methyl-1-oxo-2,3,5,6,7,8-hexahydro-1H-cyclopenta[b]naphthalen-2-yl)-acetamide, is hydrogenated over Pd/C in acetic acid/H2SO4 and the products are saponified with NaOH according to the procedures described for the preparation of 2-methyl-indan-2-ylamine. The resulting product mixture is recrystallised repeatedly from hexane to give the title compound, a single isomer.
