反応手順
0.1683 g (0.75 millimol) of palladium acetate, 9.49 g (37.5 millimols) of naphthalene-2,6-dicarboxylic acid dichloride, 9.38 g (93.75 millimols) of ethyl acrylate and 13.89 g (75 millimols) of tri-n-butylamine, in 150 ml of p-xylene, are stirred for 2 hours at 120° C. The crude product is chromatographed on silica gel in methylene chloride, and is then recrystallised from cyclohexane. 4.11 g (34% of theory) of yellow crystals, of melting point 150°-51° C., are obtained. Analysis for C20H20O4 : calculated C 74.06%, H 6.22%, O 19.73%; found C 73.85%, H 6.41%, O 19.56%.
