반응 단계
A mixture of 350 milligrams (0.001 mols) of 5-aminofluorescein and 300 milligrams (excess) of maleic anhydride were mixed in 5.0 milliliters of glacial acetic acid and the mixture was stirred at ambient temperature for 24 hours. The yellow product formed was filtered off and washed three times with diethyl ether. 420 Milligrams of fluorescein-maleamic acid was obtained. l.R (KBR) showed bands at 2.55; 3.28; 3.38; 4.05; 5.85; 6.30; 6.52; 6.88; 6.90; 7.70; 8.34; 8.52; and 8.30μ.
