반응 단계
A solution of 4 g (16 mmol) of 5,6,7, 8-tetrahydro-5,5,8,8-tetramethylnaphthalene-2-carbonyl chloride and 4 g (16 mmol) of methyl 4-bromomethylbenzoate in 20 ml of dimethoxyethane was added dropwise to a solution or suspension of 0.56 g of bis(triphenylphosphine)palladium(II) dichloride and 2.1 g of zinc powder in 40 ml of dimethoxyethane at room temperature. The reaction mixture was then refluxed for 6 h. After cooling, solids were filtered off and the filtrate was heated with active carbon and filtered hot. The filtrate was concentrated and yielded after recrystallization 3x from methanol and finally from isopropanol 0.9 g of the title compound of melting point 103°-104° C.
