Nitration of N-ethoxy~arbonyl-[U-~~C]aniline with two equivalents of nitric acid in sulfuric acid afforded N-ethoxycarbonyl-2,4-dinitro-[U-l4C]aniline which was deprotected quantitatively to P,Cdinitro-[U-l4C]aniline. Selective hydrogenation provided 99.5% radiochemically pure [U-I 4C]nitrophenylene
