実験手順: 5.0 g of 2,6-dimethyl-4-propionylanisole and 2.8 g of phenylhydrazine were dissolved in 30 ml of ethanol. A small amount of acetic acid was added under reflux for 30 minutes. After cooling, 10 ml of a 20% ethanol solution of hydrogen chloride was added to the reaction mixture, and the mixture was refluxed for 1.5 hours. The reaction mixture was cooled, poured into water, extracted with benzene, washed with water, and dried. The solvent was evaporated, and the residue was crystallized from benzene-hexane to give 4.3 g of 2-(4-methoxy-3,5-dimethylphenyl)-3-methylindole. under reflux for 30 minutes After cooling the mixture was refluxed for 1.5 hours The reaction mixture was cooled extracted with benzene washed with water dried The solvent was evaporated the residue was crystallized from benzene-hexane

実験手順: 13.6 g of 2,6-dimethylanisole was dissolved in 30 ml of methylene chloride, and 16 g of anhydrous aluminum chloride was added. Then, with water cooling, 11 g of propionyl chloride was added dropwise. The mixture was stirred at room temperature for 1 hour. The reaction mixture was poured into ice water, and the organic layer was separated and washed with water. The solvent was evaporated to give 18.7 g of 2,6-dimethyl-4-propionylanisole. the organic layer was separated washed with water The solvent was evaporated
