Description

Friedel-Crafts acylation of [U-14C]p-dichlorobenzene with 3,6-dichlorophthalic anhydride in aluminium bromide melt followed by oleum cyclization afforded [U-14C]-1,4,5,6-tetra-chloroanthroquinone. Potassium fluoride mediated amidosulfonation followed by hydrolysis gave [U-14C]-1,4,5,8- tetraaminoanthraquinone with specific activity 39.7 mCi/mmol in 5.6% radiochemical yield. (author)
