Versuchsvorschrift

8 Grams of 4-methyl-7-crotyloxy-1-indanone was suspended in 50 ml of tetrahydronaphthalene. The suspension was refluxed by heating for 9 hours under argon gas atmosphere. The reaction mixture was purified by means of a silica gel column chromatography (eluent: n-hexane, then a mixture of n-hexane: dichloromethane=2:1) and was recrystallized from a mixture of dichloromethane with n-hexane to obtain 5.44 g of 4-methyl-6-(1-methyl-2-propenyl)-1-indanone.
