실험 절차
From 100.0 g. (0.155 mole) of N-(3-methylaminocarbonyl-5-amino-2,4,6-triiodobenzoyl)-β-alanine (IX c), m.p. about 190° C., in 190 ml. of dimethylacetamide, 70.1 g. (66.0%) of the above product, m.p. 295°-297°C. (under decomposition) is obtained with the addition of 28.7 ml. of acetyl chloride analogously to Example 14 and after reprecipitation from aqueous ammonia with hydrochloric acid.
