Versuchsvorschrift

The reaction is diluted with water and extracted with dichloromethane. After drying (Na2SO4) the solvent is removed to give an oil. The product is purified by chromatography (silica, ethyl acetate/hexane) to give a geometrical mixture of isomers containing 2-Methyl-1,2,6,7,8,9-hexahydro-cyclopenta[.a.]naphthalen-3-one and the title compound.
