Step 1; Preparation of 3-iodo-N,N-diethylphthalamidic acid . To 15 ml of an acetonitrile solution containing 2.0 g of 3-iodophthalic anhydride was added dropwise 0.7 g of diethylamine under ice-cooling and stirring, and after completion of the dropwise addition, the mixture was stirred at room temperature for 2 hours. After completion of the reaction, the precipitated solid were collected by filtration, washed with a small amount of acetonitrile to obtain 1.5 g of the objective material as pale yellowish crystals. Melting point 120.0 to 122.0C1H NMR (CDCl3, Me4Si, 300MHz) delta 8.28 (bs, 1 H), 8.05 (d, J=8.5Hz, 1 H), 7.98 (d, J=8.5Hz, 1 H), 7.0-7.2 (m, 1 H), 3.67 (q, J=7.2Hz, 2H), 3.49 (q, J=7.2Hz, 2H), 1.12 (t, J=7.2Hz, 3H), 1.10 (t, J=7.2Hz, 3H).
