실험 절차
5.6 g (0.02 mole) of 6-(3-chloropropionyl)-1,2,3,4-tetrahydro-1,1,4,4-tetramethylnapthalene and 3.3 were stirred for 1 hour at room temperature. Thereafter, a solution of 3.6 g (0.025 mole) of methyl 4-formylbenzoate and 1 g of 3-benzyl-5-(2-hydroxyethyl)-4-methylthiazolium chloride in 10 ml of dimethylformamide was added dropwise. Stirring was continued for 1 hour, after which the mixture was poured onto ice/water and extracted twice with ethyl acetate, and the combined organic extracts were washed several times with water, dried over magnesium sulfate and evaporated down. 3.7 g of 1-(4-carbomethoxyphenyl)-4-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl)-butane-1,4-dione of melting point 139°-141° C. were obtained from the residue (6.4 g) after recrystallization from ethanol. 2-(4-Carbomethoxyphenyl)-5-(5,6,7,8-tetrahy-dro-5,5,8,8-tetramethyl-2-naphthalenyl)-thiophene:
